Subject: Retire git-export.
X-Git-Tag: v0.99.8~81
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=0fe51391a80919870f94ddb442df234bb2223f3b;p=git.git

Retire git-export.

git-export was done as a concept example on how easy it is to export
the git data to something else. It's much less powerful than any
number of trivial one-liner scripts now, and real exporters would not
ever use git-export.

It's obviously much less powerful than "git-whatchanged", or just
about any combination of git-rev-list + git-diff-tree.
