$ cat svn2git.sh 
#! /bin/sh
# Simple script to mirror an existing SVN repository as a git repository.
# Full project history will be imported
#
# Usage:
# svn2git.sh name-of-module
# name-of-module - the name of the GIT repository that we wish to create
# svn/module/path - the optional SVN path of the module being mirrored.
#                   Defaults to the name of the GIT repository being created

$ cat checkout-git-svn.sh
#!/bin/sh
# Simple script to checkout a project from git and tie up SVN commits. Should be a lot faster than git svn clone
# Initial parameter is the name of the git /svn module. Optional second parameter is the SVN path. This allows us to manage more complex SVN modules, which may be nested rather than at the top level
