How to print source code from the command line

a2ps gives you individual control of features, but shortcuts are
available for giving you a nice output.  The -M medium business I use to
set up the print margins for my output, and the -2 is a "2 up" shortcut
for printing two pages per sheet, doing all the fiddly things like
lines/sheet and columns automatically.  The only customization I used
was the -C for my line number every 5 lines, which I find less intrusive
than a line number every line.  Use the -o filename to output the
postscript to a file, and look at it with evince before printing if you
want.  As to where these predefineds are set up, I'd start looking in
the /etc/a2ps*.cfg files (The -MLetterdj margins are explicit in the
a2ps.cfg).
