a script to re-write JIRA subject lines for easier GMail threading

[Philip Zeyliger <ph...@cloudera.com>]

If you subscribe to core-dev and use gmail, you might be interested in a
quick script I wrote to log into my e-mail and re-write JIRA subject lines,
to fix the threading in gmail.  This way "Updated", "Commented", and
"Created" messages all appear in the same thread.

The code is at http://github.com/philz/jira-rewrite/tree/master .  I've
pasted in a bit of the documentation and a sample run below.

Re-writes JIRA subject lines to remove JIRA's "Updated/Commented/Created"
annotations.
JIRA's default subjects break Gmail's threading (which threads by subject
line); making the
subject line uniform unbreaks Gmail's threading.

Specifically, this looks at every message in --source, does a search and
replace
with --regex and --replace (defaults are for JIRA subject lines), and puts
the
modified message in --dest.  The original message is moved to --backup.
