So I'm (finally) writing a book, and using groff -mom macros
for typesetting.  Wanted to run what I have so far through
style(1) and diction(1), which on Linux requires one to
run the input through deroff(1) first.

Linux doesn't seem to have deroff.

So, here is my q&d solution:

$ cat mini_deroff.pl 
#!/usr/bin/perl

%roffchars = ('.',1,' ',1,"\\",1);

while(<>)
{
if(/^\.PP/) { print "\n"; }
next if (exists($roffchars{substr($_,0,1)}));
print;
}
exit 0;

Constructive comments appreciated.

BTW, if there's interest in the document processing, I have
a Makefile that eases the pain of processing, including
a "make look" rule that gens the pdf and views it.

Also, if anyone knows where there is source for a working
Linux deroff(1), would very much appreciate the pointer.
So far I found the OpenBSD one, but it seems to rely on
a lot of preprocessor macros that Linux doesn't have.

Finally, one last look on Google, and I found a version
of deroff for Debian... but it seems to be dated 1996, and doesn't
grok -mom macros.  (It is, however, written in lex, which
might be an opportunity for me to learn that lingo and
fix it...)
