	use Meta::Utils::File::Dir qw();

This is a library to help you do things with directories. For instance: create a directory (also creating its parents) and dying if something goes wrong, checking if a directory is empty etc...

	check_exist($)
	check_notexist($)
	fixdir($)
	get_relative_path($$)
	file_list($)
	TEST($)

empty($)

This returns a boolean value according to whether the directory is empty or not. The current implementation seems slow since it lists our all the files in that directory and checks to see that we have only one (the ".." link which points to the father...:) A speedup would be to find a better way in perl to do this... Using stat maybe ?

check_exist($)

This routine checks if a directory given to it exists. If the directory does not exist it throws an exception.

check_notexist($)

This routine checks if a directory given to it does not exist. If the directory exists it throws an exception.

fixdir($)

This routine gets a name of a file or directory and eliminated bad stuff from it: 0. [pref] slash [a] slash [..] slash [suff] is turned to [pref] slash [suff] Currently it will only do this (removed trailing slashes) using a regexp.

get_relative_path($$)

This method will return a relative path which leads from the first file or directory to the second assuming that they both start from the same root.

file_list($)

This method will return the file list in a specific directory. This method will throw eceptions if something bad happens.

TEST($)
