realpath(file)

Determine the "real" name of a file.

On Win32 (and other platforms that don't support symlinks), this should return whatever was passed (similar to the "truename" command on DOS, but at the moment doesn't handle subst'd drives).

On Unix, this will break the filename into pieces and remove all symlinks from the filename. It does not handle hard links.

file	the filename to process.

Returns: the "real" name of the passed filename.

find_file_in_path(file, path=$:, extensions=['', '.so', '.rb'])

Given a filename, search for it in path.

file	the name of the file to find
path	an array containing all the directories to search
extensions	an array containing extensions to search for

Returns: the full pathname of the file, or just the parameter file if it was not found.
