These files need to annp.tmac file to compile.  The supplied tmac.an.patch
file is the diff between the file an-old.tmac which comes with Groff 1.18.1 
and the annp.tmac macro set which the ej2ps script uses.

The generated PDF files are optimized to print on to Letter paper.  This is
set in /usr/share/groff/1.18.1/font/devps/DESC if you wish to make this
a4 or what not (look for the line that looks like "papersize /etc/papersize 
letter".

Note that this .pdf file is not perfect.  For example, there are problems
with spacing, especially with the "fi" character and the quote character.
