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...]
39 OOPS! You naughty creature! You didn't run Configure with sh!

1755 This installation shell script will examine your system and ask you questions
1756 to determine how the perl5 package should be installed. If you get
1757 stuck on a question, you may use a ! shell escape to start a subshell or
1758 execute a command. Many of the questions will have default answers in square
1759 brackets; typing carriage return will give you the default.
1761 On some of the questions which ask for file or directory names you are allowed
1762 to use the ~name construct to specify the login directory belonging to "name",
1763 even if you don't have a shell which knows about that. Questions where this is
1764 allowed will be marked "(~name ok)".
1768 dflt='Type carriage return to continue'
1772 The prompter used in this script allows you to use shell variables and
1773 backticks in your answers. You may use $1, $2, etc... to refer to the words
1774 in the default answer, as if the default line was a set of arguments given to a
1775 script shell. This means you may also use $* to repeat the whole default line,
1776 so you do not have to re-type everything to add something to the default.
1778 Everytime there is a substitution, you will have to confirm. If there is an
1779 error (e.g. an unmatched backtick), the default answer will remain unchanged
1780 and you will be prompted again.
1782 If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all
1783 the questions and use the computed defaults (or the previous answers if there
1784 was already a config.sh file). Type 'Configure -h' for a list of options.
1785 You may also start interactively and then answer '& -d' at any prompt to turn
1786 on the non-interactive behaviour for the remainder of the execution.
1792 Much effort has been expended to ensure that this shell script will run on any
1793 Unix system. If despite that it blows up on yours, your best bet is to edit
1794 Configure and run it again. If you can't run Configure for some reason,
1795 you'll have to generate a config.sh file by hand. Whatever problems you
1796 have, let me (perlbug@perl.com) know how I blew it.
1798 This installation script affects things in two ways:
1800 1) it may do direct variable substitutions on some of the files included
1802 2) it builds a config.h file for inclusion in C programs. You may edit
1803 any of these files as the need arises after running this script.
1805 If you make a mistake on a question, there is no easy way to back up to it
1806 currently. The easiest thing to do is to edit config.sh and rerun all the SH
1807 files. Configure will offer to let you do this before it runs the SH files.
