# extract_fixtures.rake | |

# I got this from Peter Gulezian <http://metoca.net/> | |
# Looks like another version is here | |
# <http://redmine.rubyforge.org/svn/trunk/lib/tasks/extract_fixtures.rake> | |
# | |
# This is the inverse of the built-in rake db:fixtures:load | |
# | |
# Usage: rake db:fixtures:extract | |
# rake db:fixtures:extract FIXTURES=foo | |
# rake db:fixtures:extract FIXTURES=foo,bar | |
# | |
