+"""Consolidate a bunch of CVS or RCS logs read from stdin.
+
+Input should be the output of a CVS or RCS logging command, e.g.
+
+    cvs log -rrelease14
+
+which dumps all log messages from release1.4 upwards (assuming that
+release 1.4 was tagged with tag 'release14').
+
+This collects all the revision records and outputs them sorted by date
+rather than by file, collapsing duplicate revision record, i.e.,
+records with the same message for different files.
+
+The -t option causes it to truncate (discard) the last revision log
+entry; this is useful when using something like the above cvs log
+command, which shows the revisions including the given tag, while you
+probably want everything *since* that tag.
+
+XXX This code was created by reverse engineering CVS 1.9 and RCS 5.7.
