#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.
