Hello, I've written a simple tool for interoperating between git and
svn.  I wrote this so I could use git to work on projects where other
developers use Subversion.  I really hate using svn, but some projects I
work on require it, and svk isn't nearly as fast nor simple as git.

Great, I was doing some testing with git-svnimport for this, but I missed
a tool to automatically commit to svn what I have in my GIT tree.

git-svn does not replace git-svnimport, git-svnimport handles branches
and tags automatically, but is too inflexible about repository layouts
to be useful for a good number of projects I follow, and of course
git-svnimport can't commit to Subversion repositories :)

I am already using git-svnimport to keep a "mirror" of some subversion
repositories, here (automatically udpated on crontab). Do you plan to
allow "integration" with repositories that are just clones of
git-svnimport'ed repositories?

It's possible, just not very obvious at the moment.  git-svn was written
as quickly as possible without regard to svnimport compatibility since I
had some repos that didn't work with svnimport to begin with.

The 'ADDITIONAL FETCH ARGUMENTS' part of the manpage is worth reading
for you.  Basically, you can define equalities
"(svn revision number)=(git commit)" as arguments to git-svn fetch to 
add parents for all the revisions it imports.

If I were you, I'd only want git-svn to care about partial history,
since you already have the rest of it from git-svnimport.  You can do
this:

	svn_revno=<last svn revision number you imported from git-svnimport>
	git_commit=<equivalent commit sha1 name of svn_revno above>
	git-svn fetch --revision $svn_revno:HEAD $svn_revno=$git_commit

I plan to keep using git-svnimport and the standard git tools to work
using the "svn mirror on git" as the main repository, but I plan to use
"git-svn commit" to commit to the SVN repositories. I want this "commit
tool" to not affect the current repository in any way, just like git-push:
only send the commits to the remote repository and don't change anything
in the local repository.

However, it seems that "git-svn commit" does some tasks assuming we
are on a "git-svn aware" repository (e.g. the "resyncing" just after
the commit). Would you accept patches to allow using "git-svn commit"
to commit changes from any GIT repository (i.e. not "svn-git aware"
repositories) to any SVN repository, just like "git-push" would work
for a GIT repository?

However, I am not sure if the easier way would be changing git-svn to
do this for me or writing a different script just for this task.

You should be 95% there just by exporting the svn_checkout_tree()
function to the command-line.  Perhaps automating reading of the
$svn_rev variable can be in order.
