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...]

1776 to determine how the perl5 package should be installed. If you get

1782 to use the ~name construct to specify the login directory belonging to "name",

1784 allowed will be marked "(~name ok)".

1793 backticks in your answers. You may use $1, $2, etc... to refer to the words
1794 in the default answer, as if the default line was a set of arguments given to a
1795 script shell. This means you may also use $* to repeat the whole default line,
1796 so you do not have to re-type everything to add something to the default.
1798 Everytime there is a substitution, you will have to confirm. If there is an
1799 error (e.g. an unmatched backtick), the default answer will remain unchanged
1800 and you will be prompted again.
1802 If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all
1803 the questions and use the computed defaults (or the previous answers if there
1804 was already a config.sh file). Type 'Configure -h' for a list of options.
1805 You may also start interactively and then answer '& -d' at any prompt to turn
1806 on the non-interactive behaviour for the remainder of the execution.
1812 Much effort has been expended to ensure that this shell script will run on any
1813 Unix system. If despite that it blows up on yours, your best bet is to edit
1814 Configure and run it again. If you can't run Configure for some reason,
1815 you'll have to generate a config.sh file by hand. Whatever problems you
1816 have, let me (perlbug@perl.com) know how I blew it.
1818 This installation script affects things in two ways:
1820 1) it may do direct variable substitutions on some of the files included
1822 2) it builds a config.h file for inclusion in C programs. You may edit
1823 any of these files as the need arises after running this script.
1825 If you make a mistake on a question, there is no easy way to back up to it
1826 currently. The easiest thing to do is to edit config.sh and rerun all the SH
1827 files. Configure will offer to let you do this before it runs the SH files.
