+#!/bin/bash
+#
+# Author: Joe Atzberger
+#
+# This script will update your git-svn repository from the 
+# SVN source repo and push to a github remote (if one exists).
+#
+# The design is (somewhat) suitable for cronjob because it:
+#   ~ only updates the local "master" branch
+#   ~ dies if it cannot switch to "master"
+#   ~ switches back to whatever branch was current initially
+#
+# However, it will fail if you cannot switch branches, (i.e. 
+# have a lot of uncommited changes).  
+#
+# WARNING: you should NOT run this in crontab on a repo you
+# are actively developing since switching branches (even
+# momentarily) in the middle of editing or runtime could
+# seriously confuse any developer.  Instead, just run it 
+# manually as needed.
+#
+# Workflow might look like:
+#   git checkout -b my_feature
+#   [ edit, edit, edit ]
+#   git commit -a
+#   ./build/tools/update_git_svn.sh
+#   git rebase master
+#   git push github my_feature
+#
