DESIGN PHILOSOPHY
-----------------
Merge tracking in Subversion is lacking and doing branched development
with Subversion is cumbersome as a result. git-svn completely forgoes
any automated merge/branch tracking on the Subversion side and leaves it
entirely up to the user on the git side. It's simply not worth it to do
a useful translation when the original signal is weak.

TRACKING MULTIPLE REPOSITORIES OR BRANCHES
------------------------------------------
This is for advanced users, most users should ignore this section.
Because git-svn does not care about relationships between different
branches or directories in a Subversion repository, git-svn has a simple
hack to allow it to track an arbitrary number of related _or_ unrelated
SVN repositories via one git repository. Simply set the GIT_SVN_ID
environment variable to a name other other than "git-svn" (the default)
and git-svn will ignore the contents of the $GIT_DIR/svn/git-svn directory
and instead do all of its work in $GIT_DIR/svn/$GIT_SVN_ID for that
invocation. The interface branch will be remotes/$GIT_SVN_ID, instead of
remotes/git-svn. Any remotes/$GIT_SVN_ID branch should never be modified
by the user outside of git-svn commands.
SVN repositories via one git repository. Simply use the --id/-i flag or
set the GIT_SVN_ID environment variable to a name other other than

$GIT_DIR/svn/$GIT_SVN_ID for that invocation. The interface branch will
