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...]

1676 This installation shell script will examine your system and ask you questions
1677 to determine how the perl5 package should be installed. If you get
1678 stuck on a question, you may use a ! shell escape to start a subshell or
1679 execute a command. Many of the questions will have default answers in square
1680 brackets; typing carriage return will give you the default.
1682 On some of the questions which ask for file or directory names you are allowed
1683 to use the ~name construct to specify the login directory belonging to "name",
1684 even if you don't have a shell which knows about that. Questions where this is
1685 allowed will be marked "(~name ok)".
1689 dflt='Type carriage return to continue'
1693 The prompter used in this script allows you to use shell variables and
1694 backticks in your answers. You may use $1, $2, etc... to refer to the words
1695 in the default answer, as if the default line was a set of arguments given to a
1696 script shell. This means you may also use $* to repeat the whole default line,
1697 so you do not have to re-type everything to add something to the default.
1699 Everytime there is a substitution, you will have to confirm. If there is an
1700 error (e.g. an unmatched backtick), the default answer will remain unchanged
1701 and you will be prompted again.
1703 If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all
1704 the questions and use the computed defaults (or the previous answers if there
1705 was already a config.sh file). Type 'Configure -h' for a list of options.
1706 You may also start interactively and then answer '& -d' at any prompt to turn
1707 on the non-interactive behaviour for the remainder of the execution.
1713 Much effort has been expended to ensure that this shell script will run on any
1714 Unix system. If despite that it blows up on yours, your best bet is to edit
1715 Configure and run it again. If you can't run Configure for some reason,
1716 you'll have to generate a config.sh file by hand. Whatever problems you
1717 have, let me (perlbug@perl.com) know how I blew it.
1719 This installation script affects things in two ways:
1721 1) it may do direct variable substitutions on some of the files included
1723 2) it builds a config.h file for inclusion in C programs. You may edit
1724 any of these files as the need arises after running this script.
1726 If you make a mistake on a question, there is no easy way to back up to it
1727 currently. The easiest thing to do is to edit config.sh and rerun all the SH
1728 files. Configure will offer to let you do this before it runs the SH files.
