 # sharun
-Run dynamically linked ELF binaries everywhere (musl and glibc are supported)
+Run dynamically linked ELF binaries everywhere (musl and glibc are supported).
+* This works with [userland-execve](https://github.com/io12/userland-execve-rust) by mapping the interpreter (such as ld-linux-x86-64.so.2) into memory, creating a stack for it (containing the auxiliary vector, arguments, and environment variables), and then jumping to the entry point with the new stack.
+* [lib4bin](https://github.com/VHSgunzo/sharun/blob/main/lib4bin) pulls out the binary file and all the libraries on which it depends, strip it (you can disable it with `STRIP=0` env var, see [lib4bin](https://github.com/VHSgunzo/sharun/blob/main/lib4bin#L15)) and forms the `bin`, `shared/{bin,lib,lib32}` directories (see [screenshots](https://github.com/VHSgunzo/sharun?tab=readme-ov-file#screenshots)) and generate a file `shared/{lib,lib32}/lib.path` with a list of all directories that contain libraries for pass it to interpreter `--library-path`. The paths in this file are specified on a new line with a `+` at the beginning and relative to the directory in which it is located.
