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...]

1799 The prompter used in this script allows you to use shell variables and
1800 backticks in your answers. You may use $1, $2, etc... to refer to the words
1801 in the default answer, as if the default line was a set of arguments given to a
1802 script shell. This means you may also use $* to repeat the whole default line,
1803 so you do not have to re-type everything to add something to the default.
1805 Everytime there is a substitution, you will have to confirm. If there is an
1806 error (e.g. an unmatched backtick), the default answer will remain unchanged
1807 and you will be prompted again.
1809 If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all
1810 the questions and use the computed defaults (or the previous answers if there
1811 was already a config.sh file). Type 'Configure -h' for a list of options.
1812 You may also start interactively and then answer '& -d' at any prompt to turn
1813 on the non-interactive behaviour for the remainder of the execution.
1819 Much effort has been expended to ensure that this shell script will run on any
1820 Unix system. If despite that it blows up on yours, your best bet is to edit
1821 Configure and run it again. If you can't run Configure for some reason,
1822 you'll have to generate a config.sh file by hand. Whatever problems you
1823 have, let me (perlbug@perl.com) know how I blew it.
1825 This installation script affects things in two ways:
1827 1) it may do direct variable substitutions on some of the files included
1829 2) it builds a config.h file for inclusion in C programs. You may edit
1830 any of these files as the need arises after running this script.
1832 If you make a mistake on a question, there is no easy way to back up to it
1833 currently. The easiest thing to do is to edit config.sh and rerun all the SH
1834 files. Configure will offer to let you do this before it runs the SH files.
