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.)

1754 This installation shell script will examine your system and ask you questions
1755 to determine how the perl5 package should be installed. If you get
1756 stuck on a question, you may use a ! shell escape to start a subshell or
1757 execute a command. Many of the questions will have default answers in square
1758 brackets; typing carriage return will give you the default.
1760 On some of the questions which ask for file or directory names you are allowed
1761 to use the ~name construct to specify the login directory belonging to "name",
1762 even if you don't have a shell which knows about that. Questions where this is
1763 allowed will be marked "(~name ok)".
1767 dflt='Type carriage return to continue'
1771 The prompter used in this script allows you to use shell variables and
1772 backticks in your answers. You may use $1, $2, etc... to refer to the words
1773 in the default answer, as if the default line was a set of arguments given to a
1774 script shell. This means you may also use $* to repeat the whole default line,
1775 so you do not have to re-type everything to add something to the default.
1777 Everytime there is a substitution, you will have to confirm. If there is an
1778 error (e.g. an unmatched backtick), the default answer will remain unchanged
1779 and you will be prompted again.
1781 If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all
1782 the questions and use the computed defaults (or the previous answers if there
1783 was already a config.sh file). Type 'Configure -h' for a list of options.
1784 You may also start interactively and then answer '& -d' at any prompt to turn
1785 on the non-interactive behaviour for the remainder of the execution.
1791 Much effort has been expended to ensure that this shell script will run on any
1792 Unix system. If despite that it blows up on yours, your best bet is to edit
1793 Configure and run it again. If you can't run Configure for some reason,
1794 you'll have to generate a config.sh file by hand. Whatever problems you
1795 have, let me (perlbug@perl.com) know how I blew it.
1797 This installation script affects things in two ways:
1799 1) it may do direct variable substitutions on some of the files included
1801 2) it builds a config.h file for inclusion in C programs. You may edit
1802 any of these files as the need arises after running this script.
1804 If you make a mistake on a question, there is no easy way to back up to it
1805 currently. The easiest thing to do is to edit config.sh and rerun all the SH
1806 files. Configure will offer to let you do this before it runs the SH files.

5245 company-wide network.
