Hi,

Here is my 5 minute attempt to create a program that extracts all
comments in a C source file containing the string "TODO":

todo_comments = File.
  open(ARGV[0], "r").
  read.
  scan(/\/\*.*?\*\//m).
  delete_if { |c| c !~ /TODO/ }

It works fine, but I really would like to have access to the line number
where the scan matches. Is that easy to accomplish or do I have to
rethink the structure of the program from scratch?
