Puppet::Type.type(:file_line).provide(:ruby) do
+ desc <<-DOC
+ @summary
+ This type allows puppet to manage small config files.
+
+ The implementation matches the full line, including whitespace at the
+ beginning and end. If the line is not contained in the given file, Puppet
+ will append the line to the end of the file to ensure the desired state.
+ Multiple resources may be declared to manage multiple lines in the same file.
