-In addition to parsing WikiMedia XML data dumps into a tab-separated tabular
-format, wikiq extracts article diffs and can execute arbitrary Perl-compatible
-regular expressions against the additions and deletions which differentiate any
-revision from the previous.  Any number of regular expressions may be supplied
-on the command line, and may be tagged using the '-n' option.

-MD5 checksums are used at runtime for precise detection of reversions.

 contains the revision ID of the revision which was reverted to.
