Subject: [PATCH v6 07/40] Add Git/Packet.pm from parts of t0021/rot13-filter.pl
Date: Sat, 16 Sep 2017 10:06:58 +0200 [thread overview]
Message-ID: <20170916080731.13925-8-chriscool@tuxfamily.org> (raw)
In-Reply-To: <20170916080731.13925-1-chriscool@tuxfamily.org>
And while at it let's simplify t0021/rot13-filter.pl by
using Git/Packet.pm.
This will make it possible to reuse packet related
functions in other test scripts.
