Re: [Groff] Help with crop marks code

[Clarke Echols]

Here's how I set up crop marks on an 8.5 x 11-inch sheet of paper for
10 business cards.  It's simple, works, and is easy to modify for other
uses.  I use \v and \l to produce the marks.

My Thunderbird emailer breaks lines over a certain width, so some lines
are continued on the next line (I think all of the botched lines are
comments with trailing asterisks on next line when it displays.  Your
results may or may not have the problem).

Just run and print it, and you can see how it works.
