pretty-printer for email messages and other text files

 The mp program will pretty print various files for you. It can be used
 in conjunction with a mail reading utility for producing a pretty print
 of your mail items. It can be used with a news reading tool to pretty
 print news articles. Digests can also be printed, and this version can
 pretty print ordinary ASCII files as well. Support for personal
 organiser printing was added into the last released version. There are
 numerous configuration options to allow you to adjust the way mp
 generates its output.
