(Yes, this is a new feature right before the 2.1 release. No, I can't imagine this would seriously break anybody's code. In fact, most users of this script are probably *happy* to see this addition.)

"""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'). Note the trailing
|
|
colon!
|
|
|
|
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
|
|
from their output.
