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.)

1742 This installation shell script will examine your system and ask you questions
1743 to determine how the perl5 package should be installed. If you get
1744 stuck on a question, you may use a ! shell escape to start a subshell or
1745 execute a command. Many of the questions will have default answers in square
1746 brackets; typing carriage return will give you the default.
1748 On some of the questions which ask for file or directory names you are allowed
1749 to use the ~name construct to specify the login directory belonging to "name",
1750 even if you don't have a shell which knows about that. Questions where this is
1751 allowed will be marked "(~name ok)".
1755 dflt='Type carriage return to continue'
1759 The prompter used in this script allows you to use shell variables and
1760 backticks in your answers. You may use $1, $2, etc... to refer to the words
1761 in the default answer, as if the default line was a set of arguments given to a
1762 script shell. This means you may also use $* to repeat the whole default line,
1763 so you do not have to re-type everything to add something to the default.
1765 Everytime there is a substitution, you will have to confirm. If there is an
1766 error (e.g. an unmatched backtick), the default answer will remain unchanged
1767 and you will be prompted again.
1769 If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all
1770 the questions and use the computed defaults (or the previous answers if there
1771 was already a config.sh file). Type 'Configure -h' for a list of options.
1772 You may also start interactively and then answer '& -d' at any prompt to turn
1773 on the non-interactive behaviour for the remainder of the execution.
1779 Much effort has been expended to ensure that this shell script will run on any
1780 Unix system. If despite that it blows up on yours, your best bet is to edit
1781 Configure and run it again. If you can't run Configure for some reason,
1782 you'll have to generate a config.sh file by hand. Whatever problems you
1783 have, let me (perlbug@perl.com) know how I blew it.
1785 This installation script affects things in two ways:
1787 1) it may do direct variable substitutions on some of the files included
1789 2) it builds a config.h file for inclusion in C programs. You may edit
1790 any of these files as the need arises after running this script.
1792 If you make a mistake on a question, there is no easy way to back up to it
1793 currently. The easiest thing to do is to edit config.sh and rerun all the SH
1794 files. Configure will offer to let you do this before it runs the SH files.

5122 The installation process will also create a directory for
5123 vendor-supplied add-ons. Vendors who supply perl with their system
5124 may find it convenient to place all vendor-supplied files in this
5125 directory rather than in the main distribution directory. This will
5126 ease upgrades between binary-compatible maintenance versions of perl.
5128 Of course you may also use these directories in whatever way you see
5129 fit. For example, you might use them to access modules shared over a
5130 company-wide network.
5132 The default answer should be fine for most people.
5133 This causes further questions about vendor add-ons to be skipped
5134 and no vendor-specific directories will be configured for perl.
