Subject: Add "commit" helper script
X-Git-Tag: v0.99~411
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=a3e870f2e2bcacc80d5b81d7b77c15a7928a9082;p=git.git

Add "commit" helper script

This is meant to make raw git not hugely less usable than something
like raw CVS. I want to make a 1.0 release of the plumbing, and the
actual commit part was just too intimidating.
