Sigh. Unfortunately, -ms is no more widely available than -mm. If you want to
write generic troff, you have either accept some limitations, or provide your
own macros. For many people, providing your own macros is NOT an easy task
for anything more than the simple items. Another alternative is to provide
both -mm and -ms alternatives and hope that that covers 99% of the interested
people.

Here is one attempt at writing a combination version which can shift from -mm
to -ms based on the command line setting of the v register. I hope it helps
someone.

Instructions: replace the beginning of Jessie's posting with the following,
down to the first .P. To print with -mm, use the command:

	tbl < [this_lis] | [your_troff] -mm | [your_print_command]

To print with -ms, use the command:

	tbl < [this_lis] | [your_troff] -ms -rv1 | [your_print_command]
