RootUtils.h

// Dear emacs, this is -*-c++-*-

// Since ROOT writes to "the current directory", one has to remember 
// to cd() all the time to the right one.  
// ChdirTemp helps to keep track of the calls. 
// It can be used, for example, in write(TDirectory *) function of an 
// object which calls ROOT's Write() on ROOT objects.
//
