    perlcile - a Code Intelligence Language Engine for the Perl language

    Module Usage:
        from perlcile import scan_purelang
        content = open("foo.pl", "r").read()
        scan_purelang(content, "foo.pl")

    Command-line Usage:
        perlcile.py [<options>...] [<Perl file>]

    Options:
        -h, --help          dump this help and exit
        -V, --version       dump this script's version and exit
        -v, --verbose       verbose output, use twice for more verbose output
        -f, --filename <path>   specify the filename of the file content
                            passed in on stdin, this is used for the "path"
                            attribute of the emitted <file> tag.
        --md5=<string>      md5 hash for the input
        --mtime=<secs>      modification time for output info, in #secs since
                            1/1/70.
        -L, --language <name>
                            the language of the file being scanned
        -c, --clock         print timing info for scans (CIX is not printed)

    One or more Perl files can be specified as arguments or content can be
    passed in on stdin. A directory can also be specified, in which case
    all .pl files in that directory are scanned.

    This is a Language Engine for the Code Intelligence (codeintel) system.
    Code Intelligence XML format. See:
        http://specs.activestate.com/Komodo_3.0/func/code_intelligence.html
        http://specs.tl.activestate.com/kd/kd-0100.html

    The command-line interface will return non-zero iff the scan failed.
