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...]

1760 This installation shell script will examine your system and ask you questions
1761 to determine how the perl5 package should be installed. If you get
1762 stuck on a question, you may use a ! shell escape to start a subshell or
1763 execute a command. Many of the questions will have default answers in square
1764 brackets; typing carriage return will give you the default.
1766 On some of the questions which ask for file or directory names you are allowed
1767 to use the ~name construct to specify the login directory belonging to "name",
1768 even if you don't have a shell which knows about that. Questions where this is
1769 allowed will be marked "(~name ok)".
1773 dflt='Type carriage return to continue'
1777 The prompter used in this script allows you to use shell variables and
1778 backticks in your answers. You may use $1, $2, etc... to refer to the words
1779 in the default answer, as if the default line was a set of arguments given to a
1780 script shell. This means you may also use $* to repeat the whole default line,
1781 so you do not have to re-type everything to add something to the default.
1783 Everytime there is a substitution, you will have to confirm. If there is an
1784 error (e.g. an unmatched backtick), the default answer will remain unchanged
1785 and you will be prompted again.
1787 If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all
1788 the questions and use the computed defaults (or the previous answers if there
1789 was already a config.sh file). Type 'Configure -h' for a list of options.
1790 You may also start interactively and then answer '& -d' at any prompt to turn
1791 on the non-interactive behaviour for the remainder of the execution.
1797 Much effort has been expended to ensure that this shell script will run on any
1798 Unix system. If despite that it blows up on yours, your best bet is to edit
1799 Configure and run it again. If you can't run Configure for some reason,
1800 you'll have to generate a config.sh file by hand. Whatever problems you
1801 have, let me (perlbug@perl.com) know how I blew it.
1803 This installation script affects things in two ways:
1805 1) it may do direct variable substitutions on some of the files included
1807 2) it builds a config.h file for inclusion in C programs. You may edit
1808 any of these files as the need arises after running this script.
1810 If you make a mistake on a question, there is no easy way to back up to it
1811 currently. The easiest thing to do is to edit config.sh and rerun all the SH
1812 files. Configure will offer to let you do this before it runs the SH files.

5243 The installation process will also create a directory for
5244 vendor-supplied add-ons. Vendors who supply perl with their system
5245 may find it convenient to place all vendor-supplied files in this
5246 directory rather than in the main distribution directory. This will
5247 ease upgrades between binary-compatible maintenance versions of perl.
5249 Of course you may also use these directories in whatever way you see
5250 fit. For example, you might use them to access modules shared over a
5251 company-wide network.
