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.)

1753 This installation shell script will examine your system and ask you questions
1754 to determine how the perl5 package should be installed. If you get
1755 stuck on a question, you may use a ! shell escape to start a subshell or
1756 execute a command. Many of the questions will have default answers in square
1757 brackets; typing carriage return will give you the default.
1759 On some of the questions which ask for file or directory names you are allowed
1760 to use the ~name construct to specify the login directory belonging to "name",
1761 even if you don't have a shell which knows about that. Questions where this is
1762 allowed will be marked "(~name ok)".
1766 dflt='Type carriage return to continue'
1770 The prompter used in this script allows you to use shell variables and
1771 backticks in your answers. You may use $1, $2, etc... to refer to the words
1772 in the default answer, as if the default line was a set of arguments given to a
1773 script shell. This means you may also use $* to repeat the whole default line,
1774 so you do not have to re-type everything to add something to the default.
1776 Everytime there is a substitution, you will have to confirm. If there is an
1777 error (e.g. an unmatched backtick), the default answer will remain unchanged
1778 and you will be prompted again.
1780 If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all
1781 the questions and use the computed defaults (or the previous answers if there
1782 was already a config.sh file). Type 'Configure -h' for a list of options.
1783 You may also start interactively and then answer '& -d' at any prompt to turn
1784 on the non-interactive behaviour for the remainder of the execution.
1790 Much effort has been expended to ensure that this shell script will run on any
1791 Unix system. If despite that it blows up on yours, your best bet is to edit
1792 Configure and run it again. If you can't run Configure for some reason,
1793 you'll have to generate a config.sh file by hand. Whatever problems you
1794 have, let me (perlbug@perl.com) know how I blew it.
1796 This installation script affects things in two ways:
1798 1) it may do direct variable substitutions on some of the files included
1800 2) it builds a config.h file for inclusion in C programs. You may edit
1801 any of these files as the need arises after running this script.
1803 If you make a mistake on a question, there is no easy way to back up to it
1804 currently. The easiest thing to do is to edit config.sh and rerun all the SH
1805 files. Configure will offer to let you do this before it runs the SH files.

5242 Of course you may also use these directories in whatever way you see

5244 company-wide network.
