# MySQL. Versions 4.1 and 5.0 are recommended.
#
# Install the MYSQL driver
# gem install mysql2
#
# Ensure the MySQL gem is defined in your Gemfile
# gem 'mysql2'
#
# And be sure to use new-style password hashing:

development:
adapter: mysql
encoding: utf8
reconnect: false
database: ctfs
pool: 5

# Warning: The database defined as "test" will be erased and
# re-generated from your development database when you run "rake".
