$! 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

$! "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.

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

$!
$! 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
