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...]

1750 This installation shell script will examine your system and ask you questions
1751 to determine how the perl5 package should be installed. If you get
1752 stuck on a question, you may use a ! shell escape to start a subshell or
1753 execute a command. Many of the questions will have default answers in square
1754 brackets; typing carriage return will give you the default.
1756 On some of the questions which ask for file or directory names you are allowed
1757 to use the ~name construct to specify the login directory belonging to "name",
1758 even if you don't have a shell which knows about that. Questions where this is
1759 allowed will be marked "(~name ok)".
1763 dflt='Type carriage return to continue'
1767 The prompter used in this script allows you to use shell variables and
1768 backticks in your answers. You may use $1, $2, etc... to refer to the words
1769 in the default answer, as if the default line was a set of arguments given to a
1770 script shell. This means you may also use $* to repeat the whole default line,
1771 so you do not have to re-type everything to add something to the default.
1773 Everytime there is a substitution, you will have to confirm. If there is an
1774 error (e.g. an unmatched backtick), the default answer will remain unchanged
1775 and you will be prompted again.
1777 If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all
1778 the questions and use the computed defaults (or the previous answers if there
1779 was already a config.sh file). Type 'Configure -h' for a list of options.
1780 You may also start interactively and then answer '& -d' at any prompt to turn
1781 on the non-interactive behaviour for the remainder of the execution.
1787 Much effort has been expended to ensure that this shell script will run on any
1788 Unix system. If despite that it blows up on yours, your best bet is to edit
1789 Configure and run it again. If you can't run Configure for some reason,
1790 you'll have to generate a config.sh file by hand. Whatever problems you
1791 have, let me (perlbug@perl.com) know how I blew it.
1793 This installation script affects things in two ways:
1795 1) it may do direct variable substitutions on some of the files included
1797 2) it builds a config.h file for inclusion in C programs. You may edit
1798 any of these files as the need arises after running this script.
1800 If you make a mistake on a question, there is no easy way to back up to it
1801 currently. The easiest thing to do is to edit config.sh and rerun all the SH
1802 files. Configure will offer to let you do this before it runs the SH files.

5231 company-wide network.
