Subject: [meta-oe,1/1] gitpkgv: add support SRCREV_FORMAT
Date: Sat, 03 Sep 2011 23:05:17 -0000

Message-Id: <4eda9a09d7beb54d290ba6f89e04150aae3b3857.1315091074.git.otavio@ossystems.com.br>
To: openembedded-devel@lists.openembedded.org

In case of multiple GIT repositories are used, SRCREV_FORMAT will be
respected while filling it with the proper GIT information to each
revision.

This new feature needed heavy changes in the code so basically it was
a rewrote version that keeps compatibility with previous usage.
