	my($done)=Meta::Utils::File::Purge::purge($my_directory,$demo,$verbose);

This is a general utility to clean up whole directory trees from empty dirs which are created in the build process. This library utilizes the finddepth routine to do the purging, meaning it scans the directory at hand in the order of children before fathers, if a directory is empty it removes it and if a father is left empty after all children were removed it removes the father and so on...

	doit()

$demo,$verb,$done,$erro

These routines hold the data for the entire process. demo is whether the run is a dry run. verb is whether we should be verbose or not. done is whether we have anything so far. erro is whether there was an error so far.

init($$$)

This function starts up all the vars in the purge process. This is an internal routine and you should not call it directly.

doit()

This function actually does the purging. This is an internal routine and you should not call it directly.

purge($$$$)

This function purges a directory tree meaning removes all sub directories which are empty in recursion (meaning that directories which had only empty dirs in them will be removed etc.. etc.. etc..). The inputs are a directory name, demo boolean that controls whether the dirs are actually removed or not, and a verbose flag. The routine also receives a pointer of where to store the number of directories actually removed.

This routine returns a success value.
