Creates an archive out of a directory.

Uses command-lne tar as Zeta Cmponents do no compress well, and pake
relies on phar which is buggy/unstable on old php versions

@param boolean $no_top_dir when set, $sourcedir directory is not packaged as top-level dir in archive
@todo for tar formats, fix the extra "." dir packaged
