Xcode build phase script for auto-versioning

# Xcode auto-versioning script for Subversion
# by Axel Andersson, modified by Daniel Jalkut to add
# "--revision HEAD" to the svn info line, which allows
# the latest revision to always be used.

# See http://www.red-sweater.com/blog/23/automatic-build-sub-versioning-in-xcode#finalscript
