Subject: Pod typos, pod2man bugs, and miscellaneous installation comments

This patch just changed the old s2p.man page into a pod page.
I then embedded the pod into the s2p script.

+=head1 NAME
+
+s2p - Sed to Perl translator
+
+=head1 SYNOPSIS
+
+B<s2p [options] filename>
+
+=head1 DESCRIPTION
+
+I<S2p> takes a sed script specified on the command line (or from
+standard input) and produces a comparable I<perl> script on the
+standard output.
+
+=head2 Options
+
+Options include:
+
+=over 5
+
+=item B<-DE<lt>numberE<gt>>
+
+sets debugging flags.
+
+=item B<-n>
+
+specifies that this sed script was always invoked with a B<sed -n>.
+Otherwise a switch parser is prepended to the front of the script.
+
+=item B<-p>
+
+specifies that this sed script was never invoked with a B<sed -n>.
+Otherwise a switch parser is prepended to the front of the script.

+
+=head2 Considerations
+
+The perl script produced looks very sed-ish, and there may very well
+be better ways to express what you want to do in perl.  For instance,
+s2p does not make any use of the split operator, but you might want
+to.
+
+The perl script you end up with may be either faster or slower than
+the original sed script.  If you're only interested in speed you'll
+just have to try it both ways.  Of course, if you want to do something
+sed doesn't do, you have no choice.  It's often possible to speed up
+the perl script by various methods, such as deleting all references to
+$\ and chop.
+
+=head1 ENVIRONMENT
+
+S2p uses no environment variables.
