# If for some reason you're not using git-svn, and you need to convert an svn
# repo's svn:ignore properties to a .gitignore file, this may be of use to you.
#
# To do the conversion, utter the following from the top level svn directory:
#     svn propget svn:ignore -R | git-ignore-from-svn:ignore
# This will write the files to ignore to standard out. You will probably want to
# redirect that to a .gitignore file or something similar.
#
# Note one VERY LARGE CAVEAT in this script: If any of the files that are
# ignored contain " - " (that is, a blank followed by a dash followed by a
# blank), this script will NOT work. This is a limitation because that is the
# delimeter used by svn propget -R to separate a directory from the files it is
# ignoring. Someone who cares more could fix this problem.
