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...]

1744 This installation shell script will examine your system and ask you questions
1745 to determine how the perl5 package should be installed. If you get
1746 stuck on a question, you may use a ! shell escape to start a subshell or
1747 execute a command. Many of the questions will have default answers in square
1748 brackets; typing carriage return will give you the default.
1750 On some of the questions which ask for file or directory names you are allowed
1751 to use the ~name construct to specify the login directory belonging to "name",
1752 even if you don't have a shell which knows about that. Questions where this is
1753 allowed will be marked "(~name ok)".
1757 dflt='Type carriage return to continue'
1761 The prompter used in this script allows you to use shell variables and
1762 backticks in your answers. You may use $1, $2, etc... to refer to the words
1763 in the default answer, as if the default line was a set of arguments given to a
1764 script shell. This means you may also use $* to repeat the whole default line,
1765 so you do not have to re-type everything to add something to the default.
1767 Everytime there is a substitution, you will have to confirm. If there is an
1768 error (e.g. an unmatched backtick), the default answer will remain unchanged
1769 and you will be prompted again.
1771 If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all
1772 the questions and use the computed defaults (or the previous answers if there
1773 was already a config.sh file). Type 'Configure -h' for a list of options.
1774 You may also start interactively and then answer '& -d' at any prompt to turn
1775 on the non-interactive behaviour for the remainder of the execution.
1781 Much effort has been expended to ensure that this shell script will run on any
1782 Unix system. If despite that it blows up on yours, your best bet is to edit
1783 Configure and run it again. If you can't run Configure for some reason,
1784 you'll have to generate a config.sh file by hand. Whatever problems you
1785 have, let me (perlbug@perl.com) know how I blew it.
1787 This installation script affects things in two ways:
1789 1) it may do direct variable substitutions on some of the files included
1791 2) it builds a config.h file for inclusion in C programs. You may edit
1792 any of these files as the need arises after running this script.
1794 If you make a mistake on a question, there is no easy way to back up to it
1795 currently. The easiest thing to do is to edit config.sh and rerun all the SH
1796 files. Configure will offer to let you do this before it runs the SH files.

5131 The installation process will also create a directory for
5132 vendor-supplied add-ons. Vendors who supply perl with their system
5133 may find it convenient to place all vendor-supplied files in this
5134 directory rather than in the main distribution directory. This will
5135 ease upgrades between binary-compatible maintenance versions of perl.
5137 Of course you may also use these directories in whatever way you see
5138 fit. For example, you might use them to access modules shared over a
5139 company-wide network.
5141 The default answer should be fine for most people.
5142 This causes further questions about vendor add-ons to be skipped
5143 and no vendor-specific directories will be configured for perl.
