 features:
 
-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.

 output:
 
 wikiq generates these fields for each revision:
 
 title, articleid, revid, timestamp, anon, editor, editorid, minor,
-text_length, text_entropy, text_md5, reversion, additions_size, deletions_size
-.... and additional fields for each regex executed against add/delete diffs
+text_length, text_md5, reversion, additions_size, deletions_size
+.... and additional fields for each regex executed against content or
+added/deleted diffs
 
 Boolean fields are TRUE/FALSE except in the case of reversion, which is blank
 unless the article is a revert to a previous revision, in which case, it
 contains the revision ID of the revision which was reverted to.
