########################################
# Quick and dirty script for cloning an svn branch with git without pulling the entire repo history
#
# Usage: git-svn-clone.sh <URL> <LOCAL_OUTPUT_PATH>
#   e.g. git-svn-clone.sh http://myserver.com/svn/branches/feature-1.0 feature-1.0
#
########################################

URL=$1
LOCAL_OUTPUT_PATH=$2

########################################
# Fetch the revision from the svn log, stopping at the first commit in a branch
#  This is obviously gross - clean up with some
########################################
# Output will be something like:
#------------------------------------------------------------------------
#r62344 | somedeveloper | 2014-04-07 15:36:45 -0500 (Mon, 07 Apr 2014)
#------------------------------------------------------------------------
#r62281 | somedeveloper | 2014-04-03 19:25:04 -0500 (Thu, 03 Apr 2014)
#------------------------------------------------------------------------
#r62280 | somedeveloper | 2014-04-03 19:23:44 -0500 (Thu, 03 Apr 2014)
#------------------------------------------------------------------------
#  ^-- we want the revision from the second-to-last line
