Subject: exit status: Introdude Debian::Dgit::ExitStatus
X-Git-Tag: archive/debian/5.0~52
X-Git-Url: http://www.chiark.greenend.org.uk/ucgi/~ianmdlvl/git?p=dgit.git;a=commitdiff_plain;h=1d6ce76f63bcbe787e7184a1fa5aa568a2a18873;ds=sidebyside

exit status: Introdude Debian::Dgit::ExitStatus

No callers yet.

Also, no version for dgit-infrastructure.  The one perl script in
dgit-infrastructure that cares a lot about its exit status
(dgit-repos-policy-debian) already has an END { } and uses _exit,
which is a bit like our approach here, but simpler.
