$! 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

$!

$! Thank you!!!!

$! "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.

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.

Many of the questions will have default answers in square
