$! OpenVMS configuration procedure for Perl -- do not attempt to run under DOS
$ sav_ver = 'F$VERIFY(0)'
$ on control_y then goto clean_up
$! SET VERIFY
$!
$! For example, if you unpacked perl into: [USER.PERL-5n...] then you will 
$! want to cd into the tree and execute Configure:
$!
$! $ SET DEFAULT [USER.PERL5_xxx]
$! $ @Configure 
$!
$! or
$!
$! $ SET DEFAULT [USER.PERL5_xxx]
$! $ @Configure "-des"
$!
$! That's it. If you get into a bind trying to build perl on VMS then 
$! definitely read through the README.VMS file.
$! Beyond that send email to vmsperl@perl.org

$! Adapted and converted from Larry Wall & Andy Dougherty's
$! "Configure generated by metaconfig 3.0 PL60." by Peter Prymmer
$! (a Bourne sh[ell] script for configuring the installation of perl 
$! on non-VMS systems) in the perl5.002|3 epoch (spring/summer 1996)
$! with much valuable help from Charles Bailey & 
$! the whole VMSPerl crew.

$! Sebastian Bazley's request: close the CONFIG handle with /NOLOG

$! This construct was tested to be not a problem as far back as
$! VMS V5.5-2, hopefully earlier versions are OK as well.

This installation shell script will examine your system and ask you questions
to determine how the perl5 package should be installed. If you get
stuck on a question, you may use a ^C or ^Y shell escape to STOP this
process, edit something, then restart this process as you just did.

$!
$!  - build a config.sh for VMS Perl.
$!  - use built config.sh to take config_h.SH -> config.h
$!  - also take vms/descrip_mms.template -> descrip.mms (VMS Makefile)
$!              vms/Makefile.in -> Makefile. (VMS GNU Makefile?)
$!              vms/Makefile.SH -> Makefile. (VMS GNU Makefile?)
$!
$! Note for folks from other platforms changing things in here:
$!
$!   Fancy changes (based on compiler capabilities or VMS version or
$!   whatever) are tricky, so go ahead and punt on those.
$!
$!   Simple changes, though (say, always setting something to 1, or undef,
$!   or something like that) are straightforward.  Adding a new constant 
$!   item for the ultimately created config.sh requires at least one 
$!   (possibly more) line(s) to this file.
$!
$!   Add a line in the format:
$!
$!     $ WC "foo='undef'"
$!
$!   somewhere between the line tagged '##BEGIN WRITE NEW CONSTANTS HERE##'
$!   and the one tagged '##END WRITE NEW CONSTANTS HERE##' (note the order
$!   is sorted ASCII and corresponds to the output of config.sh in the 
$!   Bourne shell version of Configure).
$!   Be very careful with quoting, as it can be tricky.
$!   For example if instead of a constant string like 'undef' or 'define' 
$!   you wanted to add something to VMS's config.sh that looks like:
$!
$!     blank_string=''
$!
$!   then add a line that looks like this before the 
$!   '##END WRITE NEW CONSTANTS HERE##' tagged line:
$!
$!     $ WC "blank_string='" + "'"
$!
$!   (+ is the string concatenator and "''var'" has the effect 
$!    of "${var}" in perl or sh, but "'const'" is not interpolated).
$!
$!   Note that unitialized variables, such as a line like:
$!
$!     $ WC "new_var='" + new_var + "'"
$!
$!   should be avoided unless new_var has a value assigned prior 
$!   to that line (think of perl's -w warnings).
$!
$!     %DCL-W-UNDSYM, undefined symbol - check validity and spelling
