usage = <<EOF
Usage: ack.rb <regexp> <directory or filename>
The regular expression can be across multiple lines, and is _not_ escaped by default.
For example:
  ack.rb 'end\\nend' .
will find all files in the current directory that have two 'end' statements across two lines

# This is a simple program that reads in a Ruby ERB file, and parses

# converting the ERB tags (<% %> and <%= %>) to XML tags (<erb-disp/>
