# Beware, strange "installer" coming your way.
#
# = Text configuration installer
#
# This installer pushes simple configuration into a file.
#
# == Example Usage
#
# Installing magic_beans into apache2.conf
#
# package :magic_beans do
# push_text 'magic_beans', '/etc/apache2/apache2.conf'
# end
#
# If you user has access to 'sudo' and theres a file that requires
# priveledges, you can pass :sudo => true
#
# package :magic_beans do
# push_text 'magic_beans', '/etc/apache2/apache2.conf', :sudo => true
# end
#
# A special verify step exists for this very installer
# its known as file_contains, it will test that a file indeed
# contains a substring that you send it.
