+
+Basic Installation
+==================
+
+   Briefly, the shell commands `./configure; make; make install' should
+configure, build, and install this package.  The following
+more-detailed instructions are generic; see the `README' file for
+instructions specific to this package.  Some packages provide this
+`INSTALL' file but do not implement all of the features documented
+below.  The lack of an optional feature in a given package is not
+necessarily a bug.  More recommendations for GNU packages can be found
+in *note Makefile Conventions: (standards)Makefile Conventions.
+
+   The `configure' shell script attempts to guess correct values for
+various system-dependent variables used during compilation.  It uses
+those values to create a `Makefile' in each directory of the package.
+It may also create one or more `.h' files containing system-dependent
+definitions.  Finally, it creates a shell script `config.status' that
+you can run in the future to recreate the current configuration, and a
+file `config.log' containing compiler output (useful mainly for
+debugging `configure').
+
+   It can also use an optional file (typically called `config.cache'
+and enabled with `--cache-file=config.cache' or simply `-C') that saves
+the results of its tests to speed up reconfiguring.  Caching is
+disabled by default to prevent problems with accidental use of stale
+cache files.
+
+   If you need to do unusual things to compile the package, please try
+to figure out how `configure' could check whether to do them, and mail
+diffs or instructions to the address given in the `README' so they can
+be considered for the next release.  If you are using the cache, and at
+some point `config.cache' contains results you don't want to keep, you
+may remove or edit it.
+
+   The file `configure.ac' (or `configure.in') is used to create
+`configure' by a program called `autoconf'.  You need `configure.ac' if
+you want to change it or regenerate `configure' using a newer version
+of `autoconf'.
+
+   The simplest way to compile this package is:
+
+  1. `cd' to the directory containing the package's source code and type
+     `./configure' to configure the package for your system.
+
+     Running `configure' might take a while.  While running, it prints
+     some messages telling which features it is checking for.
+
+  2. Type `make' to compile the package.
+
+  3. Optionally, type `make check' to run any self-tests that come with
+     the package, generally using the just-built uninstalled binaries.
+
+  4. Type `make install' to install the programs and any data files and
+     documentation.  When installing into a prefix owned by root, it is
+     recommended that the package be configured and built as a regular
+     user, and only the `make install' phase executed with root
+     privileges.
+
+  5. Optionally, type `make installcheck' to repeat any self-tests, but
+     this time using the binaries in their final installed location.
+     This target does not install anything.  Running this target as a
+     regular user, particularly if the prior `make install' required
+     root privileges, verifies that the installation completed
+     correctly.
+
+  6. You can remove the program binaries and object files from the
+     source code directory by typing `make clean'.  To also remove the
+     files that `configure' created (so you can compile the package for
+     a different kind of computer), type `make distclean'.  There is
+     also a `make maintainer-clean' target, but that is intended mainly
+     for the package's developers.  If you use it, you may have to get
+     all sorts of other programs in order to regenerate files that came
+     with the distribution.
+
+  7. Often, you can also type `make uninstall' to remove the installed
+     files again.  In practice, not all packages have tested that
+     uninstallation works correctly, even though it is required by the
+     GNU Coding Standards.
+
+  8. Some packages, particularly those that use Automake, provide `make
+     distcheck', which can by used by developers to test that all other
+     targets like `make install' and `make uninstall' work correctly.
+     This target is generally not run by end users.
+
+Compilers and Options
+=====================
+
+   Some systems require unusual options for compilation or linking that
+the `configure' script does not know about.  Run `./configure --help'
+for details on some of the pertinent environment variables.
+
+   You can give `configure' initial values for configuration parameters
+by setting variables in the command line or in the environment.  Here
+is an example:
+
+     ./configure CC=c99 CFLAGS=-g LIBS=-lposix
+
+   *Note Defining Variables::, for more details.
+
+Compiling For Multiple Architectures
+====================================
+
+   You can compile the package for more than one kind of computer at the
+same time, by placing the object files for each architecture in their
+own directory.  To do this, you can use GNU `make'.  `cd' to the
+directory where you want the object files and executables to go and run
+the `configure' script.  `configure' automatically checks for the
+source code in the directory that `configure' is in and in `..'.  This
+is known as a "VPATH" build.
+
+   With a non-GNU `make', it is safer to compile the package for one
+architecture at a time in the source code directory.  After you have
+installed the package for one architecture, use `make distclean' before
+reconfiguring for another architecture.
+
+   On MacOS X 10.5 and later systems, you can create libraries and
+executables that work on multiple system types--known as "fat" or
+"universal" binaries--by specifying multiple `-arch' options to the
+compiler but only a single `-arch' option to the preprocessor.  Like
+this:
+
+     ./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
+                 CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
+                 CPP="gcc -E" CXXCPP="g++ -E"
+
+   This is not guaranteed to produce working output in all cases, you
+may have to build one architecture at a time and combine the results
+using the `lipo' tool if you have problems.
+
+Installation Names
+==================
+
+   By default, `make install' installs the package's commands under
+`/usr/local/bin', include files under `/usr/local/include', etc.  You
+can specify an installation prefix other than `/usr/local' by giving
+`configure' the option `--prefix=PREFIX', where PREFIX must be an
+absolute file name.
+
+   You can specify separate installation prefixes for
+architecture-specific files and architecture-independent files.  If you
+pass the option `--exec-prefix=PREFIX' to `configure', the package uses
+PREFIX as the prefix for installing programs and libraries.
+Documentation and other data files still use the regular prefix.
+
+   In addition, if you use an unusual directory layout you can give
+options like `--bindir=DIR' to specify different values for particular
+kinds of files.  Run `configure --help' for a list of the directories
+you can set and what kinds of files go in them.  In general, the
+default for these options is expressed in terms of `${prefix}', so that
+specifying just `--prefix' will affect all of the other directory
+specifications that were not explicitly provided.
+
+   The most portable way to affect installation locations is to pass the
+correct locations to `configure'; however, many packages provide one or
+both of the following shortcuts of passing variable assignments to the
+`make install' command line to change installation locations without
+having to reconfigure or recompile.
+
+   The first method involves providing an override variable for each
+affected directory.  For example, `make install
+prefix=/alternate/directory' will choose an alternate location for all
+directory configuration variables that were expressed in terms of
+`${prefix}'.  Any directories that were specified during `configure',
+but not in terms of `${prefix}', must each be overridden at install
+time for the entire installation to be relocated.  The approach of
+makefile variable overrides for each directory variable is required by
+the GNU Coding Standards, and ideally causes no recompilation.
+However, some platforms have known limitations with the semantics of
+shared libraries that end up requiring recompilation when using this
+method, particularly noticeable in packages that use GNU Libtool.
+
+   The second method involves providing the `DESTDIR' variable.  For
+example, `make install DESTDIR=/alternate/directory' will prepend
+`/alternate/directory' before all installation names.  The approach of
+`DESTDIR' overrides is not required by the GNU Coding Standards, and
+does not work on platforms that have drive letters.  On the other hand,
+it does better at avoiding recompilation issues, and works well even
+when some directory options were not specified in terms of `${prefix}'
+at `configure' time.
+
+Optional Features
+=================
+
+   If the package supports it, you can cause programs to be installed
+with an extra prefix or suffix on their names by giving `configure' the
+option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
+
+   Some packages pay attention to `--enable-FEATURE' options to
+`configure', where FEATURE indicates an optional part of the package.
+They may also pay attention to `--with-PACKAGE' options, where PACKAGE
+is something like `gnu-as' or `x' (for the X Window System).  The
+`README' should mention any `--enable-' and `--with-' options that the
+package recognizes.
+
+   For packages that use the X Window System, `configure' can usually
+find the X include and library files automatically, but if it doesn't,
+you can use the `configure' options `--x-includes=DIR' and
+`--x-libraries=DIR' to specify their locations.
+
+   Some packages offer the ability to configure how verbose the
+execution of `make' will be.  For these packages, running `./configure
+--enable-silent-rules' sets the default to minimal output, which can be
+overridden with `make V=1'; while running `./configure
+--disable-silent-rules' sets the default to verbose, which can be
+overridden with `make V=0'.
+
+Particular systems
+==================
+
+   On HP-UX, the default C compiler is not ANSI C compatible.  If GNU
+CC is not installed, it is recommended to use the following options in
+order to use an ANSI C compiler:
+
+     ./configure CC="cc -Ae -D_XOPEN_SOURCE=500"
+
+and if that doesn't work, install pre-built binaries of GCC for HP-UX.
+
+   On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot
+parse its `<wchar.h>' header file.  The option `-nodtk' can be used as
+a workaround.  If GNU CC is not installed, it is therefore recommended
+to try
+
+     ./configure CC="cc"
+
+and if that doesn't work, try
+
+     ./configure CC="cc -nodtk"
+
+   On Solaris, don't put `/usr/ucb' early in your `PATH'.  This
+directory contains several dysfunctional programs; working variants of
+these programs are available in `/usr/bin'.  So, if you need `/usr/ucb'
+in your `PATH', put it _after_ `/usr/bin'.
+
+   On Haiku, software installed for all users goes in `/boot/common',
+not `/usr/local'.  It is recommended to use the following options:
+
+     ./configure --prefix=/boot/common
+
+Specifying the System Type
+==========================
+
+   There may be some features `configure' cannot figure out
+automatically, but needs to determine by the type of machine the package
+will run on.  Usually, assuming the package is built to be run on the
+_same_ architectures, `configure' can figure that out, but if it prints
+a message saying it cannot guess the machine type, give it the
+`--build=TYPE' option.  TYPE can either be a short name for the system
+type, such as `sun4', or a canonical name which has the form:
+
+     CPU-COMPANY-SYSTEM
+
+where SYSTEM can have one of these forms:
+
+     OS
+     KERNEL-OS
+
+   See the file `config.sub' for the possible values of each field.  If
+`config.sub' isn't included in this package, then this package doesn't
+need to know the machine type.
+
+   If you are _building_ compiler tools for cross-compiling, you should
+use the option `--target=TYPE' to select the type of system they will
+produce code for.
+
+   If you want to _use_ a cross compiler, that generates code for a
+platform different from the build platform, you should specify the
+"host" platform (i.e., that on which the generated programs will
+eventually be run) with `--host=TYPE'.
+
+Sharing Defaults
+================
+
+   If you want to set default values for `configure' scripts to share,
+you can create a site shell script called `config.site' that gives
+default values for variables like `CC', `cache_file', and `prefix'.
+`configure' looks for `PREFIX/share/config.site' if it exists, then
+`PREFIX/etc/config.site' if it exists.  Or, you can set the
+`CONFIG_SITE' environment variable to the location of the site script.
+A warning: not all `configure' scripts look for a site script.
+
+Defining Variables
+==================
+
+   Variables not defined in a site shell script can be set in the
+environment passed to `configure'.  However, some packages may run
+configure again during the build, and the customized values of these
+variables may be lost.  In order to avoid this problem, you should set
+them in the `configure' command line, using `VAR=value'.  For example:
+
+     ./configure CC=/usr/local2/bin/gcc
+
+causes the specified `gcc' to be used as the C compiler (unless it is
+overridden in the site shell script).
+
+Unfortunately, this technique does not work for `CONFIG_SHELL' due to
+an Autoconf bug.  Until the bug is fixed you can use this workaround:
+
+     CONFIG_SHELL=/bin/bash /bin/bash ./configure CONFIG_SHELL=/bin/bash
+
+`configure' Invocation
+======================
+
+   `configure' recognizes the following options to control how it
+operates.
+
+`--help'
+`-h'
+     Print a summary of all of the options to `configure', and exit.
+
+`--help=short'
+`--help=recursive'
+     Print a summary of the options unique to this package's
+     `configure', and exit.  The `short' variant lists options used
+     only in the top level, while the `recursive' variant lists options
+     also present in any nested packages.
+
+`--version'
+`-V'
+     Print the version of Autoconf used to generate the `configure'
+     script, and exit.
+
+`--cache-file=FILE'
+     Enable the cache: use and save the results of the tests in FILE,
+     traditionally `config.cache'.  FILE defaults to `/dev/null' to
+     disable caching.
+
+`--config-cache'
+`-C'
+     Alias for `--cache-file=config.cache'.
+
+`--quiet'
+`--silent'
+`-q'
+     Do not print messages saying which checks are being made.  To
+     suppress all normal output, redirect it to `/dev/null' (any error
+     messages will still be shown).
+
+`--srcdir=DIR'
+     Look for the package's source code in directory DIR.  Usually
+     `configure' can determine that directory automatically.
+
+`--prefix=DIR'
+     Use DIR as the installation prefix.  *note Installation Names::
+     for more details, including other options available for fine-tuning
+     the installation locations.
+
+`--no-create'
+`-n'
+     Run the configure checks, but stop before creating any output
+     files.
+
+`configure' also accepts some other, not widely useful, options.  Run
+`configure --help' for more details.
 
-                   Installing Heyu on a Unix-like system.
-
-(This file is duplicated as both INSTALL and README.INSTALL, in the
-event your case-insensitive file system overwrites INSTALL with the
-install script.)
-
-Heyu requires a reasonable compiler (GCC works well), the 'make' program,
-and the development header (.h) files.  Many OS distributions will either
-install these by default or provide a visible option to include the
-"development package" during OS installation.  But some of the newer OS's
-do not, e.g., with Ubuntu Linux it's necessary to afterward execute the
-command 'apt-get install build-essential'. 
-
-Note: If you're upgrading from a previous version of Heyu, run 'heyu stop'
-under that version before proceeding.
-
-Quickstart:
-    sh ./Configure  [option]   (As a normal user)
-    make                       (As a normal user)
-    su                         (Become superuser)
-    make install 	       (As superuser)
-    exit                       (Revert to normal user)
-    heyu info		       (As a normal user, to test installation)
-
-(The 'make install' requires that you have write permissions to
-/usr/local/bin, man page, and other directories.)
-
-Ubuntu Linux users should execute 'sudo make install' rather than
-the three commands 'su', 'make install', and 'exit'.
-
-*** Kindly report any compile errors or warnings to the author.***
-
-It can take 5-8 seconds to set up the heyu_relay daemon and initialize
-the CM11A interface the first time Heyu is run, e.g., with 'heyu info'.
-
-Running 'heyu help' will display the long list of Heyu commands.
-These are further explained in the man page heyu(1).
-
-CUSTOMIZING
------------
-The Configure script creates a Makefile by running 'uname -s' and then
-adding known good configuration options to the Makefile.  The contents
-of Makefile.in is then appended to the Makefile.  Changes to the makefile
-should be made in Configure or Makefile.in.
-
-If Configure can not figure out what your system is, you can try
-sh ./Configure generic
-    or
-sh ./Configure sysv
-
-If those don't work, we'll have to figure it out by hand. Please contact
-the author so your discoveries can be integrated into the next release.
-
-SERIAL PORTS
-------------
-Many newer computers don't have built-in RS232 serial ports, only USB
-ports.  For these computers a USB-Serial adapter is required to connect
-the CM11A.  Before purchasing a USB-Serial adapter, verify that the driver
-for your OS is available, either built-in to the OS, provided with the
-adapter on a companion disc, or downloadable from the adapter
-manufacturer's website.
-
-If you have a choice, select an adapter with an FTDI chipset over one
-with a Prolific chipset.  One dealer who specifies the chipset
-and supported operating systems for each adapter model for sale is
-ByteRunner (http://ww.byterunner.com).
-
-Drivers for adapters with a Prolific PL2303 chipset can often be found
-at http://www.prolific.com.tw/eng/downloads.asp?ID=31
-
-For Linux, the serial device name for a USB-Serial adapter will normally
-be /dev/ttyUSBx, where x = 0 for the first adapter plugged into the
-USB port and higher numbers for subsequent adapters.
-
-Note: The International 230V version of the CM11 sold in Europe and
-elsewhere is now usually provided with a USB cable in addition to the
-standard RS232 cable.  Many Linux users have experienced lockups and
-other problem with this USB cable (based on a Prolific chipset) which
-disappeared when they switched to a regular USB-Serial adapter.
-
-OPTIONS
-------- 
-By default, Heyu allocates space for 32 common flags, 32 counters, and
-32 user countdown timers.  The number of each of these can be increased
-at compile time with switches -flags=NN, -counters=NN, and -timers=NN.
-The specified NN must be in the range 1-1024 and will be rounded up to
-the nearest multiple of 32, e.g.,
-
-   sh ./Configure -flags=64  -timers=75
-
-will allocate space for 64 flags and 96 timers, the latter because
-the specified 75 is rounded up to 96.  The number of counters will
-remain 32.
-  
-By default, support for the X10 CM17A "Firecracker" device is compiled
-into Heyu.  As there is no known version of this device available which
-transmits at frequencies other than the 310 MHz used for transceivers
-in North America, users outside this region may wish to compile without
-CM17A support. Since the CM17A is both powered and actuated by the DTR
-and RTS serial lines, support for this device might as well also be
-omitted if your serial port hardware does not support these lines.
-To do so, run the Configure step mentioned above with the '-nocm17a'
-switch, i.e.,
-
-    sh ./Configure -nocm17a
-
-By default, support for Extended Type 0 (Shutter and Shade) commands
-is compiled into Heyu.  As there is only one module known to support
-these commands (the 230V, 50Hz Marmitek SW10 Shutter Motor Controller
-sold in Europe), this support may be omitted by using Configure with
-the '-noext0' switch, i.e., 
-
-   sh ./Configure -noext0
-
-By default, support for RFXSensors is compiled into Heyu. RFXSensors
-require a WGL W800RF32 or RFXCOM X10 RF receiver as well as a RFXSensor
-transmitter.  This support may be omitted by including the '-norfxs'
-switch with Configure, i.e.,
-
-   sh ./Configure -norfxs
-
-By default, support for RFXMeters is compiled into Heyu. RFXMeters
-requires a 433.92 MHz RFXCOM X10 RF receiver as well as the RFXMeter
-transmitter.  This support may be omitted by including the '-norfxm' switch
-with Configure, i.e.,
-
-   sh ./Configure -norfxm
-
-By default, support for the Digimax 210 remote thermostat is compiled
-into Heyu. The Digimax requires a 433.92 MHz RFXCOM X10 RF receiver as
-well as the Digimax transmitter.  This support may be omitted by
-including the '-nodmx' switch with Configure, i.e.,
-
-   sh ./Configure -nodmx
-
-By default, support for Oregon RF sensors is compilied into Heyu.
-Oregon sensor support requires a 433.92 MHz RFXCOM X10 RF receiver
-as well as a supported model of Oregon sensor.  This support may be
-omitted by including the '-noore' switch with Configure, i.e.,
-
-   sh ./Configure -noore
-
-By default, support for signals received from KaKu and HomeEasy
-transmitters is compiled into Heyu.  KaKu/HomeEasy support requires a
-433.92 MHz RFXCOM X10 RF receiver.  This support may be omitted
-by including the '-nokaku' switch with Configure, i.e.,
-
-   sh ./Configure -nokaku
-
-
-Notes for Mac OS X:
--------------------
-The heyu executable is installed in directory /usr/local/bin, which
-is not on the Mac's default PATH.  You will have to add this directory
-to your $PATH.  Similarly you may have to add the man page directory
-/usr/local/man to your $MANPATH (or the /usr/share/misc/man.conf file
-for newer versions of OS X which have deprecated $MANPATH).
-
-Newer Macs don't have an actual RS232 serial port, only a USB port,
-and a USB/Serial adapter is required.  The manufacturer's adapter
-driver will usually add two or more different devices in /dev
-(and often with "usbserial" as part of the name).  You'll have
-to experiment to see which one works with Heyu by trying the
-different names in the TTY directive in the heyu configuration
-file.  The device name which also includes "cu" rather than "tty"
-has been found to work on the (few) Macs tested thusfar.
-
-
-Notes for AT&T SysV r4:
-----------------------
-The function uname(1) used to determine the system type for
-Configure does not distinguish this OS from other sysv systems.
-Supply the system type parameter "attsvr4" to Configure, i.e.,
-run 'sh ./Configure attsvr4'.
-
-Notes for OpenSolaris:
----------------------
-The directories in which the Heyu binary executable and man pages
-are installed are set per the OpenSolaris system conventions to:
-  BIN = /opt/heyu/bin
-  MAN = /opt/heyu/man/man1
-  MAN5 = /opt/heyu/man/man5
-However for a virgin OS installation, none of these directories
-are on the system's PATH/MANPATH and the user is responsible
-for adding them to the PATH/MANPATH in order to have full use of
-Heyu.
-
-The user may alternatively rerun Configure for "OpenSolaris_BSD", i.e.,
-  sh ./Configure opensolaris_bsd
-which will set the directories using the BSD convention under
-the /usr/local tree, which however may be deleted when OpenSolaris
-is upgraded.
-
-Some older versions of OpenSolaris, in particular SXCE (Solaris
-Express Community Edition), may encounter an error when running
-'make install' like "test: argument expected".  If this occurs,
-change the first line of file install.sh to read "#!/bin/ksh".

-                     HEYU (version 1) Program overview
-
-This program operates an X10 module via a CM11A computer interface. It is
-based on the program X10 by Larry Cambell as modified by Paul Fox. All but a
-few functions have been changed enough that they no longer interwork with
-the original. I think this justifies issuing the program as 'heyu' instead
-of 'x10'.
-
-The program name comes from the old joke about having a 3rd person in the
-house. Ida No was the one frequently blamed when things went wrong. In my
-house it was the frequently heard yells of "Heyu! Turn off the lights!"
-A poor joke, but I like it.
-
-The program is strictly command line driven, and works well with crontab.
-Crontab can be used to schedule events. You can also upload timers and
-macros to the CM11's memory.
-
-The program comes complete with source code, sample config files, MAN pages
-an executable binary. The program has options to allow you to:
-
-   * Get the date and time from the interface
-   * Get information about current settings and module states
-   * Turn an X10 module on or off
-   * Dim or brighten an X10 module
-   * Monitor all data sent to or from the CM11A
-   * Get the status of intelligent X10 modules (rr501 for instance)
-   * Set the X10 clock from the computer's clock (time and date)
-   * Zero out the macro and event memory of the X10
-   * Upload macros and timers
-   * preset the dim level of advanced two way devices
-
-As of version 1.27, Heyu has the ability to send a schedule of events to the
-CM11A. This enables timers and macros.
-
-The people at X10 have informed me that there is no way to download (to the
-computer) the events stored in the CM11A. That being the case, I wrote
-programs that will load the events and macros from local data files. This
-will erase whatever has been stored there, but I guess that's the way it has
-to be.
-
-This should compile on any Linux system. It should also compile on any other
-BSDish or SYSV system. Just edit the #define in the make file. Make install
-will try to install the man page and the program. The makefile has defines
-for these locations.
-
-See the original README in Larry Campbell's program for some nice info on
-the cp290 and the history of the program. See the original for some really
-niffty uses using scheduling and macros.
-
-There are two demo programs included with heyu, monit and x10biff.
-
-   * The monit program will turn off your monitor based on idle time. It's
-     the ultimate screen saver.
-   * The x10biff program will flash a light to let you know that you have
-     E-mail.

+
+                   Installing Heyu on a Unix-like system.
+
+Heyu requires a reasonable compiler (GCC works well), the 'make' program,
+and the development header (.h) files.  Many OS distributions will either
+install these by default or provide a visible option to include the
+"development package" during OS installation.  But some of the newer OS's
+do not, e.g., with Ubuntu Linux it's necessary to afterward execute the
+command 'apt-get install build-essential'. 
+
+Note: If you're upgrading from a previous version of Heyu, run 'heyu stop'
+under that version before proceeding.
+
+Quickstart:
+    sh ./Configure.sh [option] (As a normal user)
+    make                       (As a normal user)
+    su                         (Become superuser)
+    make install 	       (As superuser)
+    exit                       (Revert to normal user)
+    heyu info		       (As a normal user, to test installation)
+
+(The 'make install' requires that you have write permissions to
+/usr/local/bin, man page, and other directories.)
+
+Ubuntu Linux users should execute 'sudo make install' rather than
+the three commands 'su', 'make install', and 'exit'.
+
+Advanced users and package maintainers may also wish to refer to a
+dedicated section at the bottom of this file.
+
+*** Kindly report any compile errors or warnings to the author.***
+
+It can take 5-8 seconds to set up the heyu_relay daemon and initialize
+the CM11A interface the first time Heyu is run, e.g., with 'heyu info'.
+
+Running 'heyu help' will display the long list of Heyu commands.
+These are further explained in the man page heyu(1).
+
+CUSTOMIZING
+-----------
+The Configure.sh script creates a Makefile by running 'uname -s' and then
+passing known good options to Autoconf configure script.  The contents
+of Makefile.in is then expanded to the Makefile.  Changes to the makefile
+should be made in Configure.sh or Makefile.in.
+
+If Configure.sh can not figure out what your system is, you can try
+sh ./Configure.sh generic
+    or
+sh ./Configure.sh sysv
+
+If those don't work, we'll have to figure it out by hand. Please contact
+the author so your discoveries can be integrated into the next release.
+
+SERIAL PORTS
+------------
+Many newer computers don't have built-in RS232 serial ports, only USB
+ports.  For these computers a USB-Serial adapter is required to connect
+the CM11A.  Before purchasing a USB-Serial adapter, verify that the driver
+for your OS is available, either built-in to the OS, provided with the
+adapter on a companion disc, or downloadable from the adapter
+manufacturer's website.
+
+If you have a choice, select an adapter with an FTDI chipset over one
+with a Prolific chipset.  One dealer who specifies the chipset
+and supported operating systems for each adapter model for sale is
+ByteRunner (http://ww.byterunner.com).
+
+Drivers for adapters with a Prolific PL2303 chipset can often be found
+at http://www.prolific.com.tw/eng/downloads.asp?ID=31
+
+For Linux, the serial device name for a USB-Serial adapter will normally
+be /dev/ttyUSBx, where x = 0 for the first adapter plugged into the
+USB port and higher numbers for subsequent adapters.
+
+Note: The International 230V version of the CM11 sold in Europe and
+elsewhere is now usually provided with a USB cable in addition to the
+standard RS232 cable.  Many Linux users have experienced lockups and
+other problem with this USB cable (based on a Prolific chipset) which
+disappeared when they switched to a regular USB-Serial adapter.
+
+OPTIONS
+------- 
+By default, Heyu allocates space for 32 common flags, 32 counters, and
+32 user countdown timers.  The number of each of these can be increased
+at compile time with switches -flags=NN, -counters=NN, and -timers=NN.
+The specified NN must be in the range 1-1024 and will be rounded up to
+the nearest multiple of 32, e.g.,
+
+   sh ./Configure.sh -flags=64  -timers=75
+
+will allocate space for 64 flags and 96 timers, the latter because
+the specified 75 is rounded up to 96.  The number of counters will
+remain 32.
+  
+By default, support for the X10 CM17A "Firecracker" device is compiled
+into Heyu.  As there is no known version of this device available which
+transmits at frequencies other than the 310 MHz used for transceivers
+in North America, users outside this region may wish to compile without
+CM17A support. Since the CM17A is both powered and actuated by the DTR
+and RTS serial lines, support for this device might as well also be
+omitted if your serial port hardware does not support these lines.
+To do so, run the Configure.sh step mentioned above with the '-nocm17a'
+switch, i.e.,
+
+    sh ./Configure.sh -nocm17a
+
+By default, support for Extended Type 0 (Shutter and Shade) commands
+is compiled into Heyu.  As there is only one module known to support
+these commands (the 230V, 50Hz Marmitek SW10 Shutter Motor Controller
+sold in Europe), this support may be omitted by using Configure.sh with
+the '-noext0' switch, i.e., 
+
+   sh ./Configure.sh -noext0
+
+By default, support for RFXSensors is compiled into Heyu. RFXSensors
+require a WGL W800RF32 or RFXCOM X10 RF receiver as well as a RFXSensor
+transmitter.  This support may be omitted by including the '-norfxs'
+switch with Configure.sh, i.e.,
+
+   sh ./Configure.sh -norfxs
+
+By default, support for RFXMeters is compiled into Heyu. RFXMeters
+requires a 433.92 MHz RFXCOM X10 RF receiver as well as the RFXMeter
+transmitter.  This support may be omitted by including the '-norfxm' switch
+with Configure.sh, i.e.,
+
+   sh ./Configure.sh -norfxm
+
+By default, support for the Digimax 210 remote thermostat is compiled
+into Heyu. The Digimax requires a 433.92 MHz RFXCOM X10 RF receiver as
+well as the Digimax transmitter.  This support may be omitted by
+including the '-nodmx' switch with Configure.sh, i.e.,
+
+   sh ./Configure.sh -nodmx
+
+By default, support for Oregon RF sensors is compilied into Heyu.
+Oregon sensor support requires a 433.92 MHz RFXCOM X10 RF receiver
+as well as a supported model of Oregon sensor.  This support may be
+omitted by including the '-noore' switch with Configure.sh, i.e.,
+
+   sh ./Configure.sh -noore
+
+By default, support for signals received from KaKu and HomeEasy
+transmitters is compiled into Heyu.  KaKu/HomeEasy support requires a
+433.92 MHz RFXCOM X10 RF receiver.  This support may be omitted
+by including the '-nokaku' switch with Configure.sh, i.e.,
+
+   sh ./Configure.sh -nokaku
+
+By default, support for RFXLAN RF receiver (network version of RFXCOM)
+is compiled into Heyu.  This support may be omitted by including the
+'-norfxlan' switch with Configure.sh, i.e.,
+
+   sh ./Configur.sh -norfxlan
+
+
+Notes for Mac OS X:
+-------------------
+The heyu executable is installed in directory /usr/local/bin, which
+is not on the Mac's default PATH.  You will have to add this directory
+to your $PATH.  Similarly you may have to add the man page directory
+/usr/local/man to your $MANPATH (or the /usr/share/misc/man.conf file
+for newer versions of OS X which have deprecated $MANPATH).
+
+Newer Macs don't have an actual RS232 serial port, only a USB port,
+and a USB/Serial adapter is required.  The manufacturer's adapter
+driver will usually add two or more different devices in /dev
+(and often with "usbserial" as part of the name).  You'll have
+to experiment to see which one works with Heyu by trying the
+different names in the TTY directive in the heyu configuration
+file.  The device name which also includes "cu" rather than "tty"
+has been found to work on the (few) Macs tested thusfar.
+
+
+Notes for AT&T SysV r4:
+----------------------
+The function uname(1) used to determine the system type for
+Configure.sh does not distinguish this OS from other sysv systems.
+Supply the system type parameter "attsvr4" to Configure.sh, i.e.,
+run 'sh ./Configure.sh attsvr4'.
+
+Notes for OpenSolaris:
+---------------------
+The directories in which the Heyu binary executable and man pages
+are installed are set per the OpenSolaris system conventions to:
+  BIN = /opt/heyu/bin
+  MAN = /opt/heyu/man/man1
+  MAN5 = /opt/heyu/man/man5
+However for a virgin OS installation, none of these directories
+are on the system's PATH/MANPATH and the user is responsible
+for adding them to the PATH/MANPATH in order to have full use of
+Heyu.
+
+The user may alternatively rerun Configure.sh for "OpenSolaris_BSD",
+i.e., 'sh ./Configure.sh opensolaris_bsd',
+which will set the directories using the BSD convention under
+the /usr/local tree, which however may be deleted when OpenSolaris
+is upgraded.
+
+Some older versions of OpenSolaris, in particular SXCE (Solaris
+Express Community Edition), may encounter an error when running
+'make install' like "test: argument expected".  If this occurs,
+change the first line of file install.sh to read "#!/bin/ksh".
+
+
+Notes for advanced users and (binary) package maintainers:
+----------------------------------------------------------
+
+From now on, you can use standard Autotools methods to build your
+package instead of dealing with the old Configure.sh, Makefile.in and
+install.sh. See INSTALL for generic instructions.
+
+Default runtime directories passed through ./configure to make:
+
+SYSBASEDIR	SYSCONFDIR/heyu, or just SYSCONFDIR if already
+		containing 'heyu' in its path; for example, if you
+		specify --prefix=/opt/heyu, then SYSCONFDIR will be set
+		to /opt/heyu/etc, and SYSBASEDIR will end up as
+		SYSCONFDIR; override with CPPFLAGS='...
+		-DSYSBASEDIR=\"path\" ...'
+
+LOCKDIR		LOCALSTATEDIR/lock; override with CPPFLAGS='...
+		-DLOCKDIR=\"path\" ...'
+
+SPOOLDIR	LOCALSTATEDIR/tmp/heyu; override with CPPFLAGS='...
+		-DSPOOLDIR=\"path\" ...'
+
+
+Default installation directories passed through ./configure to 'make
+install':
+
+heyu binary	BINDIR
+
+heyu.1 man page	MANDIR/man1; override with 'man1dir=<path>' (for

-                   Installing Heyu on a Unix-like system.
-
-(This file is duplicated as both INSTALL and README.INSTALL, in the
-event your case-insensitive file system overwrites INSTALL with the
-install script.)
-
-Heyu requires a reasonable compiler (GCC works well), the 'make' program,
-and the development header (.h) files.  Many OS distributions will either
-install these by default or provide a visible option to include the
-"development package" during OS installation.  But some of the newer OS's
-do not, e.g., with Ubuntu Linux it's necessary to afterward execute the
-command 'apt-get install build-essential'. 
-
-Note: If you're upgrading from a previous version of Heyu, run 'heyu stop'
-under that version before proceeding.
-
-Quickstart:
-    sh ./Configure  [option]   (As a normal user)
-    make                       (As a normal user)
-    su                         (Become superuser)
-    make install 	       (As superuser)
-    exit                       (Revert to normal user)
-    heyu info		       (As a normal user, to test installation)
-
-(The 'make install' requires that you have write permissions to
-/usr/local/bin, man page, and other directories.)
-
-Ubuntu Linux users should execute 'sudo make install' rather than
-the three commands 'su', 'make install', and 'exit'.
-
-*** Kindly report any compile errors or warnings to the author.***
-
-It can take 5-8 seconds to set up the heyu_relay daemon and initialize
-the CM11A interface the first time Heyu is run, e.g., with 'heyu info'.
-
-Running 'heyu help' will display the long list of Heyu commands.
-These are further explained in the man page heyu(1).
-
-CUSTOMIZING
------------
-The Configure script creates a Makefile by running 'uname -s' and then
-adding known good configuration options to the Makefile.  The contents
-of Makefile.in is then appended to the Makefile.  Changes to the makefile
-should be made in Configure or Makefile.in.
-
-If Configure can not figure out what your system is, you can try
-sh ./Configure generic
-    or
-sh ./Configure sysv
-
-If those don't work, we'll have to figure it out by hand. Please contact
-the author so your discoveries can be integrated into the next release.
-
-SERIAL PORTS
-------------
-Many newer computers don't have built-in RS232 serial ports, only USB
-ports.  For these computers a USB-Serial adapter is required to connect
-the CM11A.  Before purchasing a USB-Serial adapter, verify that the driver
-for your OS is available, either built-in to the OS, provided with the
-adapter on a companion disc, or downloadable from the adapter
-manufacturer's website.
-
-If you have a choice, select an adapter with an FTDI chipset over one
-with a Prolific chipset.  One dealer who specifies the chipset
-and supported operating systems for each adapter model for sale is
-ByteRunner (http://ww.byterunner.com).
-
-Drivers for adapters with a Prolific PL2303 chipset can often be found
-at http://www.prolific.com.tw/eng/downloads.asp?ID=31
-
-For Linux, the serial device name for a USB-Serial adapter will normally
-be /dev/ttyUSBx, where x = 0 for the first adapter plugged into the
-USB port and higher numbers for subsequent adapters.
-
-Note: The International 230V version of the CM11 sold in Europe and
-elsewhere is now usually provided with a USB cable in addition to the
-standard RS232 cable.  Many Linux users have experienced lockups and
-other problem with this USB cable (based on a Prolific chipset) which
-disappeared when they switched to a regular USB-Serial adapter.
-
-OPTIONS
-------- 
-By default, Heyu allocates space for 32 common flags, 32 counters, and
-32 user countdown timers.  The number of each of these can be increased
-at compile time with switches -flags=NN, -counters=NN, and -timers=NN.
-The specified NN must be in the range 1-1024 and will be rounded up to
-the nearest multiple of 32, e.g.,
-
-   sh ./Configure -flags=64  -timers=75
-
-will allocate space for 64 flags and 96 timers, the latter because
-the specified 75 is rounded up to 96.  The number of counters will
-remain 32.
-  
-By default, support for the X10 CM17A "Firecracker" device is compiled
-into Heyu.  As there is no known version of this device available which
-transmits at frequencies other than the 310 MHz used for transceivers
-in North America, users outside this region may wish to compile without
-CM17A support. Since the CM17A is both powered and actuated by the DTR
-and RTS serial lines, support for this device might as well also be
-omitted if your serial port hardware does not support these lines.
-To do so, run the Configure step mentioned above with the '-nocm17a'
-switch, i.e.,
-
-    sh ./Configure -nocm17a
-
-By default, support for Extended Type 0 (Shutter and Shade) commands
-is compiled into Heyu.  As there is only one module known to support
-these commands (the 230V, 50Hz Marmitek SW10 Shutter Motor Controller
-sold in Europe), this support may be omitted by using Configure with
-the '-noext0' switch, i.e., 
-
-   sh ./Configure -noext0
-
-By default, support for RFXSensors is compiled into Heyu. RFXSensors
-require a WGL W800RF32 or RFXCOM X10 RF receiver as well as a RFXSensor
-transmitter.  This support may be omitted by including the '-norfxs'
-switch with Configure, i.e.,
-
-   sh ./Configure -norfxs
-
-By default, support for RFXMeters is compiled into Heyu. RFXMeters
-requires a 433.92 MHz RFXCOM X10 RF receiver as well as the RFXMeter
-transmitter.  This support may be omitted by including the '-norfxm' switch
-with Configure, i.e.,
-
-   sh ./Configure -norfxm
-
-By default, support for the Digimax 210 remote thermostat is compiled
-into Heyu. The Digimax requires a 433.92 MHz RFXCOM X10 RF receiver as
-well as the Digimax transmitter.  This support may be omitted by
-including the '-nodmx' switch with Configure, i.e.,
-
-   sh ./Configure -nodmx
-
-By default, support for Oregon RF sensors is compilied into Heyu.
-Oregon sensor support requires a 433.92 MHz RFXCOM X10 RF receiver
-as well as a supported model of Oregon sensor.  This support may be
-omitted by including the '-noore' switch with Configure, i.e.,
-
-   sh ./Configure -noore
-
-By default, support for signals received from KaKu and HomeEasy
-transmitters is compiled into Heyu.  KaKu/HomeEasy support requires a
-433.92 MHz RFXCOM X10 RF receiver.  This support may be omitted
-by including the '-nokaku' switch with Configure, i.e.,
-
-   sh ./Configure -nokaku
-
-
-Notes for Mac OS X:
--------------------
-The heyu executable is installed in directory /usr/local/bin, which
-is not on the Mac's default PATH.  You will have to add this directory
-to your $PATH.  Similarly you may have to add the man page directory
-/usr/local/man to your $MANPATH (or the /usr/share/misc/man.conf file
-for newer versions of OS X which have deprecated $MANPATH).
-
-Newer Macs don't have an actual RS232 serial port, only a USB port,
-and a USB/Serial adapter is required.  The manufacturer's adapter
-driver will usually add two or more different devices in /dev
-(and often with "usbserial" as part of the name).  You'll have
-to experiment to see which one works with Heyu by trying the
-different names in the TTY directive in the heyu configuration
-file.  The device name which also includes "cu" rather than "tty"
-has been found to work on the (few) Macs tested thusfar.
-
-
-Notes for AT&T SysV r4:
-----------------------
-The function uname(1) used to determine the system type for
-Configure does not distinguish this OS from other sysv systems.
-Supply the system type parameter "attsvr4" to Configure, i.e.,
-run 'sh ./Configure attsvr4'.
-
-Notes for OpenSolaris:
----------------------
-The directories in which the Heyu binary executable and man pages
-are installed are set per the OpenSolaris system conventions to:
-  BIN = /opt/heyu/bin
-  MAN = /opt/heyu/man/man1
-  MAN5 = /opt/heyu/man/man5
-However for a virgin OS installation, none of these directories
-are on the system's PATH/MANPATH and the user is responsible
-for adding them to the PATH/MANPATH in order to have full use of
-Heyu.
-
-The user may alternatively rerun Configure for "OpenSolaris_BSD", i.e.,
-  sh ./Configure opensolaris_bsd
-which will set the directories using the BSD convention under
-the /usr/local tree, which however may be deleted when OpenSolaris
-is upgraded.
-
-Some older versions of OpenSolaris, in particular SXCE (Solaris
-Express Community Edition), may encounter an error when running
-'make install' like "test: argument expected".  If this occurs,
-change the first line of file install.sh to read "#!/bin/ksh".

+                     HEYU (version 1) Program overview
+
+This program operates an X10 module via a CM11A computer interface. It is
+based on the program X10 by Larry Cambell as modified by Paul Fox. All but a
+few functions have been changed enough that they no longer interwork with
+the original. I think this justifies issuing the program as 'heyu' instead
+of 'x10'.
+
+The program name comes from the old joke about having a 3rd person in the
+house. Ida No was the one frequently blamed when things went wrong. In my
+house it was the frequently heard yells of "Heyu! Turn off the lights!"
+A poor joke, but I like it.
+
+The program is strictly command line driven, and works well with crontab.
+Crontab can be used to schedule events. You can also upload timers and
+macros to the CM11's memory.
+
+The program comes complete with source code, sample config files, MAN pages
+an executable binary. The program has options to allow you to:
+
+   * Get the date and time from the interface
+   * Get information about current settings and module states
+   * Turn an X10 module on or off
+   * Dim or brighten an X10 module
+   * Monitor all data sent to or from the CM11A
+   * Get the status of intelligent X10 modules (rr501 for instance)
+   * Set the X10 clock from the computer's clock (time and date)
+   * Zero out the macro and event memory of the X10
+   * Upload macros and timers
+   * preset the dim level of advanced two way devices
+
+As of version 1.27, Heyu has the ability to send a schedule of events to the
+CM11A. This enables timers and macros.
+
+The people at X10 have informed me that there is no way to download (to the
+computer) the events stored in the CM11A. That being the case, I wrote
+programs that will load the events and macros from local data files. This
+will erase whatever has been stored there, but I guess that's the way it has
+to be.
+
+This should compile on any Linux system. It should also compile on any other
+BSDish or SYSV system. Just edit the #define in the make file. Make install
+will try to install the man page and the program. The makefile has defines
+for these locations.
+
+See the original README in Larry Campbell's program for some nice info on
+the cp290 and the history of the program. See the original for some really
+niffty uses using scheduling and macros.
+
+There are two demo programs included with heyu, monit and x10biff.
+
+   * The monit program will turn off your monitor based on idle time. It's
+     the ultimate screen saver.
+   * The x10biff program will flash a light to let you know that you have
+     E-mail.

+\`configure' configures Heyu 2.10+autotools to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE.  See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+  -h, --help              display this help and exit
+      --help=short        display options specific to this package
+      --help=recursive    display the short help of all the included packages
+  -V, --version           display version information and exit
+  -q, --quiet, --silent   do not print \`checking ...' messages
+      --cache-file=FILE   cache test results in FILE [disabled]
+  -C, --config-cache      alias for \`--cache-file=config.cache'
+  -n, --no-create         do not create output files
+      --srcdir=DIR        find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+  --prefix=PREFIX         install architecture-independent files in PREFIX
+                          [$ac_default_prefix]
+  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
+                          [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.
+
+Fine tuning of the installation directories:
