# = Replace text installer
#
# This installer replaces a text with another one in a file.
#
# == Example Usage
#
# Change ssh port in /etc/ssh/sshd_config
#
# package :magic_beans do
# replace_text 'Port 22', 'Port 2500', '/etc/ssh/sshd_config'
# end
#
# If you user has access to 'sudo' and theres a file that requires
# priveledges, you can pass :sudo => true
#
# package :magic_beans do
# replace_text 'Port 22', 'Port 2500', '/etc/ssh/sshd_config', :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.
