     '''removes files not tracked by mercurial
 
     Delete files not known to mercurial, this is useful to test local and
     uncommitted changes in the otherwise clean source tree.
 
     This means that purge will delete:
      - Unknown files: files marked with "?" by "hg status"
      - Ignored files: files usually ignored by Mercurial because they match
        a pattern in a ".hgignore" file
      - Empty directories: in fact Mercurial ignores directories unless they
        contain files under source control managment
     But it will leave untouched:
      - Unmodified tracked files
      - Modified tracked files
      - New files added to the repository (with "hg add")
 
     If directories are given on the command line, only files in these
     directories are considered.
 
     Be careful with purge, you could irreversibly delete some files you
     forgot to add to the repository. If you only want to print the list of
     files that this program would delete use the --print option.
