title: What's a good library for parsing fixed-length records in Groovy?
body: <p>I want a library that I can give it a file and a config param of column length, name, and possibly type and from that get back a map of the columns of each row.</p>
  
  <p>This isn't difficult thing to do on my own, but I would be surprised if there wasn't already a great solution. I've tried searching for one, but have had no luck.</p>
