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...]

1705 This installation shell script will examine your system and ask you questions
1706 to determine how the perl5 package should be installed. If you get
1707 stuck on a question, you may use a ! shell escape to start a subshell or
1708 execute a command. Many of the questions will have default answers in square
1709 brackets; typing carriage return will give you the default.
1711 On some of the questions which ask for file or directory names you are allowed
1712 to use the ~name construct to specify the login directory belonging to "name",
1713 even if you don't have a shell which knows about that. Questions where this is
1714 allowed will be marked "(~name ok)".
1718 dflt='Type carriage return to continue'
1722 The prompter used in this script allows you to use shell variables and
1723 backticks in your answers. You may use $1, $2, etc... to refer to the words
1724 in the default answer, as if the default line was a set of arguments given to a
1725 script shell. This means you may also use $* to repeat the whole default line,
1726 so you do not have to re-type everything to add something to the default.
1728 Everytime there is a substitution, you will have to confirm. If there is an
1729 error (e.g. an unmatched backtick), the default answer will remain unchanged
1730 and you will be prompted again.
1732 If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all
1733 the questions and use the computed defaults (or the previous answers if there
1734 was already a config.sh file). Type 'Configure -h' for a list of options.
1735 You may also start interactively and then answer '& -d' at any prompt to turn
1736 on the non-interactive behaviour for the remainder of the execution.
1742 Much effort has been expended to ensure that this shell script will run on any
1743 Unix system. If despite that it blows up on yours, your best bet is to edit
1744 Configure and run it again. If you can't run Configure for some reason,
1745 you'll have to generate a config.sh file by hand. Whatever problems you
1746 have, let me (perlbug@perl.com) know how I blew it.
1748 This installation script affects things in two ways:
1750 1) it may do direct variable substitutions on some of the files included
1752 2) it builds a config.h file for inclusion in C programs. You may edit
1753 any of these files as the need arises after running this script.
1755 If you make a mistake on a question, there is no easy way to back up to it
1756 currently. The easiest thing to do is to edit config.sh and rerun all the SH
1757 files. Configure will offer to let you do this before it runs the SH files.
