+This document will help you Configure, build, test and install Perl

+
+This is a ported perl for the POSIX subsystem in BS2000 VERSION OSD
+V3.1A.  It may work on other versions, but that's the one we've tested
+it on.
 
 You may need the following GNU programs in order to install perl:
 
-gzip:

 We used version 1.2.4, which could be installed out of the box with
 one failure during 'make check'.
 
-bison:
+=head2 bison
 
 The yacc coming with BS2000 POSIX didn't work for us.  So we had to
 use bison.  We had to make a few changes to perl in order to use the
 pure (reentrant) parser of bison.  We used version 1.25, but we had to
 add a few changes due to EBCDIC.

 To extract an ASCII tar archive on BS2000 POSIX you need an ASCII
 filesystem (we used the mountpoint /usr/local/ascii for this).  Now

-INSTALLING:
-===========
+=head2 Install
 
 We have no nroff on BS2000 POSIX (yet), so we ignored any errors while
 installing the documentation.
 
 
-USING PERL:
-===========
+=head2 Using Perl
 
 BS2000 POSIX doesn't support the shebang notation
-('#!/usr/local/bin/perl'), so you have to use the following lines
+(C<#!/usr/local/bin/perl>), so you have to use the following lines
 instead:
 
 : # use perl
     eval 'exec /usr/local/bin/perl -S $0 ${1+"$@"}'
