=head1 SYNOPSIS
This document will help you Configure, build, test and install Perl
-on OS/390 Unix System Services.
+on OS/390 (aka z/OS) Unix System Services.
=head1 DESCRIPTION
You may need to carry out some system configuration tasks before
running the Configure script for Perl.

+=head2 Tools
+
+The z/OS Unix Tools and Toys list may prove helpful and contains links
+to ports of much of the software helpful for building Perl.

Some people have reported encountering "Out of memory!" errors while
trying to build Perl using GNU make binaries. If you encounter such
Recent perl test suite is quite memory hunrgy. In addition to the comments
above on memory limitations it is also worth checking for _CEE_RUNOPTS
in your environment. Perl now has (in miniperlmain.c) a C #pragma
-to set CEE run options, but the enviroment variable wins.

The important parts of that are the second argument (the increment) to HEAP,
and allowing the stack to be "Above the (16M) line". If the heap
