  3. $! # This script is designed to provide a handy summary of the configuration
  4. $! # information being used to build perl. This is especially useful if you
  5. $! # are requesting help from comp.lang.perl.misc on usenet or via mail.

  7. $! DCL-ified by Peter Prymmer <pvhp@lns62.lns.cornell.edu> 22-DEC-1995

  14. $! Incorporates Charles Bailey's ideas about bootstrapping system info - 
  15. $! myconfig.com is now callable as a "myconfig" target in your maker and
  16. $! may even work if miniperl.exe and config.sh files fail to be made.
  17. $! Thus if: 
  18. $!      MMK/DESCRIP=[.VMS]                             !(or MMS or MAKE)
  19. $! does not work then try:
  20. $!      MMK/DESCRIP=[.VMS]/OUTPUT=MYPERLBUILD.PROBLEM  !(or MMS or MAKE)
  21. $! Then discuss the MYPERLBUILD.PROBLEM file with a local expert.
  22. $! If that still does not work then try:
  23. $!      MMK/DESCRIP=[.VMS]/OUT=MYNONFIG.OUT MYCONFIG   !(or MMS or MAKE)
  24. $! send output (MYNONFIG.OUT) to an outside expert and ask politely for help.
