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.)

1761 This installation shell script will examine your system and ask you questions
1762 to determine how the perl5 package should be installed. If you get
1763 stuck on a question, you may use a ! shell escape to start a subshell or
1764 execute a command. Many of the questions will have default answers in square
1765 brackets; typing carriage return will give you the default.
1767 On some of the questions which ask for file or directory names you are allowed
1768 to use the ~name construct to specify the login directory belonging to "name",
1769 even if you don't have a shell which knows about that. Questions where this is
1770 allowed will be marked "(~name ok)".
1774 dflt='Type carriage return to continue'
1778 The prompter used in this script allows you to use shell variables and
1779 backticks in your answers. You may use $1, $2, etc... to refer to the words
1780 in the default answer, as if the default line was a set of arguments given to a
1781 script shell. This means you may also use $* to repeat the whole default line,
1782 so you do not have to re-type everything to add something to the default.
1784 Everytime there is a substitution, you will have to confirm. If there is an
1785 error (e.g. an unmatched backtick), the default answer will remain unchanged
1786 and you will be prompted again.
1788 If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all
1789 the questions and use the computed defaults (or the previous answers if there
1790 was already a config.sh file). Type 'Configure -h' for a list of options.
1791 You may also start interactively and then answer '& -d' at any prompt to turn
1792 on the non-interactive behaviour for the remainder of the execution.
1798 Much effort has been expended to ensure that this shell script will run on any
1799 Unix system. If despite that it blows up on yours, your best bet is to edit
1800 Configure and run it again. If you can't run Configure for some reason,
1801 you'll have to generate a config.sh file by hand. Whatever problems you
1802 have, let me (perlbug@perl.com) know how I blew it.
1804 This installation script affects things in two ways:
1806 1) it may do direct variable substitutions on some of the files included
1808 2) it builds a config.h file for inclusion in C programs. You may edit
1809 any of these files as the need arises after running this script.
1811 If you make a mistake on a question, there is no easy way to back up to it
1812 currently. The easiest thing to do is to edit config.sh and rerun all the SH
1813 files. Configure will offer to let you do this before it runs the SH files.

5247 vendor-supplied add-ons. Vendors who supply perl with their system
5248 may find it convenient to place all vendor-supplied files in this
5249 directory rather than in the main distribution directory. This will
5250 ease upgrades between binary-compatible maintenance versions of perl.
5252 Of course you may also use these directories in whatever way you see
5253 fit. For example, you might use them to access modules shared over a
5254 company-wide network.
