Draft for update GIT scripts

Hi all, some time ago I announced that I'm prepare draft for update scripts for work with Git. Now is attached both diff and tarball. I expect comments, objections, other suggestions :) Adjustments are as follows: + added support for branches - the current branch is detected automatically + added automatic detection gituser (from .git/config) + optimized some operations - if is not a mess, reset + clean is not called - if there is nothing to commit, commit is not called - if there is nothing to send server, push is not called - because git submodule init + update in one call update all submodules, for each git tree is called only once I was thinking about add into script commit_all_submodules check for untracked files. In order to avoid omission of renamed and new files. What is your opinion? Slavek --
