Subject: git-svn: allow overriding of the SVN repo root in metadata
X-Git-Tag: v1.5.1-rc1~152
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=aea736cc6db64219b946adb4ca77f5d17bc7ab77;p=git.git

git-svn: allow overriding of the SVN repo root in metadata

This feature allows users to create repositories from alternate
URLs.  For example, an administrator could run git-svn on the
server locally (accessing via file://) but wish to distribute
the repository with a public http:// or svn:// URL in the
metadata so users of it will see the public URL.

Config key: svn-remote.<remote>.rewriteRoot
