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...]

1775 to determine how the perl5 package should be installed. If you get

1792 backticks in your answers. You may use $1, $2, etc... to refer to the words
1793 in the default answer, as if the default line was a set of arguments given to a
1794 script shell. This means you may also use $* to repeat the whole default line,
1795 so you do not have to re-type everything to add something to the default.
1797 Everytime there is a substitution, you will have to confirm. If there is an
1798 error (e.g. an unmatched backtick), the default answer will remain unchanged
1799 and you will be prompted again.
1801 If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all
1802 the questions and use the computed defaults (or the previous answers if there
1803 was already a config.sh file). Type 'Configure -h' for a list of options.
1804 You may also start interactively and then answer '& -d' at any prompt to turn
1805 on the non-interactive behaviour for the remainder of the execution.
1811 Much effort has been expended to ensure that this shell script will run on any
1812 Unix system. If despite that it blows up on yours, your best bet is to edit
1813 Configure and run it again. If you can't run Configure for some reason,
1814 you'll have to generate a config.sh file by hand. Whatever problems you
1815 have, let me (perlbug@perl.com) know how I blew it.
1817 This installation script affects things in two ways:
1819 1) it may do direct variable substitutions on some of the files included
1821 2) it builds a config.h file for inclusion in C programs. You may edit
1822 any of these files as the need arises after running this script.
1824 If you make a mistake on a question, there is no easy way to back up to it
1825 currently. The easiest thing to do is to edit config.sh and rerun all the SH
1826 files. Configure will offer to let you do this before it runs the SH files.
