Subject: Add command line tool to update cherrymaint
X-Git-Tag: accepted/trunk/20130322.191538~8631
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=813fcdee40ed61472236553cef309e133e8c4775;p=platform%2Fupstream%2Fperl.git

Add command line tool to update cherrymaint

Usage:

  # to vote +1 to cherry pick the SHA1 'deadbeef'
  $ perl Porting/cherrymaint deadbeef

  # to mark as cherry picked
  $ perl Porting/cherrymaint --picked deadbeef

The commit ID can be any valid git revision reference, e.g. HEAD

The ssh tunnel from localhost:3000 to perl5.git.perl.org:3000 must
already exist.

LWP::UserAgent is required.
