#fixrm is a little script to limit the items on each line so the line
#is less than 72 characters. it is used by the maintainer when creating
#the README.models file for this package, and for the epson-inkjet-printer-escpr2
#slackbuild. It takes the list posted on a single long first line, and spreads
#them over as many lines as needed.
#
#paste the list from the epson website into an empty README.models and run this
#script in the same directory
