6 # (If you are trying to port this package to a machine without sh,
7 # I would suggest you have a look at the prototypical config_h.SH file
8 # and edit it to reflect your system. Some packages may include samples
9 # of config.h for certain machines, so you might look for one of those.)

15 # working with this copy of Configure, you may wish to get metaconfig.
16 # The dist-3.0 package (which contains metaconfig) was posted in
17 # comp.sources.misc and is available on CPAN under authors/id/RAM so
18 # you may fetch it yourself from your nearest archive site.)

29 SCO csh still thinks true is false. Write to SCO today and tell them that next
30 year Configure ought to "rm /bin/csh" unless they fix their blasted shell. :-)
32 (Actually, Configure ought to just patch csh in place. Hmm. Hmmmmm. All
33 we'd have to do is go in and swap the && and || tokens, wherever they are.)
35 [End of diatribe. We now return you to your regularly scheduled programming...]

1656 This installation shell script will examine your system and ask you questions
1657 to determine how the perl5 package should be installed. If you get
1658 stuck on a question, you may use a ! shell escape to start a subshell or
1659 execute a command. Many of the questions will have default answers in square
1660 brackets; typing carriage return will give you the default.
1662 On some of the questions which ask for file or directory names you are allowed
1663 to use the ~name construct to specify the login directory belonging to "name",
1664 even if you don't have a shell which knows about that. Questions where this is
1665 allowed will be marked "(~name ok)".
1669 dflt='Type carriage return to continue'
1673 The prompter used in this script allows you to use shell variables and
1674 backticks in your answers. You may use $1, $2, etc... to refer to the words
1675 in the default answer, as if the default line was a set of arguments given to a
1676 script shell. This means you may also use $* to repeat the whole default line,
1677 so you do not have to re-type everything to add something to the default.
1679 Everytime there is a substitution, you will have to confirm. If there is an
1680 error (e.g. an unmatched backtick), the default answer will remain unchanged
1681 and you will be prompted again.
1683 If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all
1684 the questions and use the computed defaults (or the previous answers if there
1685 was already a config.sh file). Type 'Configure -h' for a list of options.
1686 You may also start interactively and then answer '& -d' at any prompt to turn
1687 on the non-interactive behaviour for the remainder of the execution.
1693 Much effort has been expended to ensure that this shell script will run on any
1694 Unix system. If despite that it blows up on yours, your best bet is to edit
1695 Configure and run it again. If you can't run Configure for some reason,
1696 you'll have to generate a config.sh file by hand. Whatever problems you
1697 have, let me (perlbug@perl.com) know how I blew it.
1699 This installation script affects things in two ways:
1701 1) it may do direct variable substitutions on some of the files included
1703 2) it builds a config.h file for inclusion in C programs. You may edit
1704 any of these files as the need arises after running this script.
1706 If you make a mistake on a question, there is no easy way to back up to it
1707 currently. The easiest thing to do is to edit config.sh and rerun all the SH
1708 files. Configure will offer to let you do this before it runs the SH files.

4019 by putting the option "-lc_s" as the last thing on the cc command line when
