+# This script commits to SVN via Git-Svn dcommit. It also adds some checks to
+# make sure you're not trying to commit from master, and warns about multiple
+# commits, as they're not always intentional and could mean you're trying to
+# commit from the wrong branch.
+#
+# The script will refresh your master and branches to make sure you have an
+# up-to-date branch before committing, as that would mess up your local svn
+# setup or would at least block your commit from going through.
