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.)

1751 This installation shell script will examine your system and ask you questions
1752 to determine how the perl5 package should be installed. If you get
1753 stuck on a question, you may use a ! shell escape to start a subshell or
1754 execute a command. Many of the questions will have default answers in square
1755 brackets; typing carriage return will give you the default.
1757 On some of the questions which ask for file or directory names you are allowed
1758 to use the ~name construct to specify the login directory belonging to "name",
1759 even if you don't have a shell which knows about that. Questions where this is
1760 allowed will be marked "(~name ok)".
1764 dflt='Type carriage return to continue'
1768 The prompter used in this script allows you to use shell variables and
1769 backticks in your answers. You may use $1, $2, etc... to refer to the words
1770 in the default answer, as if the default line was a set of arguments given to a
1771 script shell. This means you may also use $* to repeat the whole default line,
1772 so you do not have to re-type everything to add something to the default.
1774 Everytime there is a substitution, you will have to confirm. If there is an
1775 error (e.g. an unmatched backtick), the default answer will remain unchanged
1776 and you will be prompted again.
1778 If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all
1779 the questions and use the computed defaults (or the previous answers if there
1780 was already a config.sh file). Type 'Configure -h' for a list of options.
1781 You may also start interactively and then answer '& -d' at any prompt to turn
1782 on the non-interactive behaviour for the remainder of the execution.
1788 Much effort has been expended to ensure that this shell script will run on any
1789 Unix system. If despite that it blows up on yours, your best bet is to edit
1790 Configure and run it again. If you can't run Configure for some reason,
1791 you'll have to generate a config.sh file by hand. Whatever problems you
1792 have, let me (perlbug@perl.com) know how I blew it.
1794 This installation script affects things in two ways:
1796 1) it may do direct variable substitutions on some of the files included
1798 2) it builds a config.h file for inclusion in C programs. You may edit
1799 any of these files as the need arises after running this script.
1801 If you make a mistake on a question, there is no easy way to back up to it
1802 currently. The easiest thing to do is to edit config.sh and rerun all the SH
1803 files. Configure will offer to let you do this before it runs the SH files.

5229 company-wide network.

7010 want to share those scripts and perl is not in a standard place

7012 a shell by starting the script with a single ':' character.
