-=head1 NAME
-
-perldos - Perl under DOS, W31, W95.
-
-=head1 SYNOPSIS
-
-These are instructions for building Perl under DOS (or w??), using
-DJGPP v2.01 or later. Under w95 long filenames are supported.
-
-=head1 DESCRIPTION
-
-Before you start, you should glance through the README file
-found in the top-level directory where the Perl distribution
-was extracted.  Make sure you read and understand the terms under
-which this software is being distributed.
-
-This port currently supports MakeMaker (the set of modules that
-is used to build extensions to perl).  Therefore, you should be
-able to build and install most extensions found in the CPAN sites.
-
-=head2 Prerequisites

-=item DJGPP
-
-DJGPP is a port of GNU C/C++ compiler and development tools to 32-bit,
-protected-mode environment on Intel 32-bit CPUs running MS-DOS and compatible
-operating systems, by DJ Delorie <dj@delorie.com> and friends.
-
-For more details (FAQ), check out the home of DJGPP at:
-
-        http://www.delorie.com/djgpp/
-
-If you have questions about DJGPP, try posting to the DJGPP newsgroup:
-comp.os.msdos.djgpp, or use the email gateway djgpp@delorie.com.
-
-You can find the full DJGPP distribution on any SimTel.Net mirror all over
-the world. Like:
-
-        ftp://ftp.simtel.net/pub/simtelnet/gnu/djgpp/v2*
-
-You need the following files to build perl (or add new modules):

-Unpack the source package F<perl5.6*.tar.gz> with djtarx. If you want

-Create a "symlink" or copy your bash.exe to sh.exe in your C<($DJDIR)/bin>

-
-        ln -s bash.exe sh.exe
-
-And make the C<SHELL> environment variable point to this F<sh.exe>:
-
-        set SHELL=c:/djgpp/bin/sh.exe (use full path name!)
-
-You can do this in F<djgpp.env> too. Add this line BEFORE any section

-If you have F<split.exe> and F<gsplit.exe> in your path, then rename 
-F<split.exe> to F<djsplit.exe>, and F<gsplit.exe> to F<split.exe>.
-Copy or link F<gecho.exe> to F<echo.exe> if you don't have F<echo.exe>.
-Copy or link F<gawk.exe> to F<awk.exe> if you don't have F<awk.exe>.
-
-=item *
-
-Chdir to the djgpp subdirectory of perl toplevel and type the following
-command:
-
-        configure.bat
-
-This will do some preprocessing then run the Configure script for you.
-The Configure script is interactive, but in most cases you
-just need to press ENTER.
-
-If the script says that your package is incomplete, and asks whether
-to continue, just answer with Y (this can only happen if you don't use
-long filenames).
-
-When Configure asks about the extensions, I suggest IO and Fcntl,
-and if you want database handling then SDBM_File or GDBM_File
-(you need to install gdbm for this one). If you want to use the
-POSIX extension (this is the default), make sure that the stack
-size of your F<cc1.exe> is at least 512kbyte (you can check this
-with: C<stubedit cc1.exe>).
-
-You can use the Configure script in non-interactive mode too.
-When I built my F<perl.exe>, I used something like this:
-
-        configure.bat -des
-
-You can find more info about Configure's command line switches in
-the F<INSTALL> file.
-
-When the script ends, and you want to change some values in the
-generated F<config.sh> file, then run
-
-        sh Configure -S
-
-after you made your modifications.
-
-IMPORTANT: if you use this C<-S> switch, be sure to delete the CONFIG
-environment variable before running the script:

-
-Type:

-
-If you're lucky you should see "All tests successful". But there can be
-a few failed subtests (less than 5 hopefully) depending on some external

-with short filenames only).
-
-=head2 Installation
-
-Type:
-
-        make install
-
-This will copy the newly compiled perl and libraries into your DJGPP
