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...]

1727 This installation shell script will examine your system and ask you questions
1728 to determine how the perl5 package should be installed. If you get
1729 stuck on a question, you may use a ! shell escape to start a subshell or
1730 execute a command. Many of the questions will have default answers in square
1731 brackets; typing carriage return will give you the default.
1733 On some of the questions which ask for file or directory names you are allowed
1734 to use the ~name construct to specify the login directory belonging to "name",
1735 even if you don't have a shell which knows about that. Questions where this is
1736 allowed will be marked "(~name ok)".
1740 dflt='Type carriage return to continue'
1744 The prompter used in this script allows you to use shell variables and
1745 backticks in your answers. You may use $1, $2, etc... to refer to the words
1746 in the default answer, as if the default line was a set of arguments given to a
1747 script shell. This means you may also use $* to repeat the whole default line,
1748 so you do not have to re-type everything to add something to the default.
1750 Everytime there is a substitution, you will have to confirm. If there is an
1751 error (e.g. an unmatched backtick), the default answer will remain unchanged
1752 and you will be prompted again.
1754 If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all
1755 the questions and use the computed defaults (or the previous answers if there
1756 was already a config.sh file). Type 'Configure -h' for a list of options.
1757 You may also start interactively and then answer '& -d' at any prompt to turn
1758 on the non-interactive behaviour for the remainder of the execution.
1764 Much effort has been expended to ensure that this shell script will run on any
1765 Unix system. If despite that it blows up on yours, your best bet is to edit
1766 Configure and run it again. If you can't run Configure for some reason,
1767 you'll have to generate a config.sh file by hand. Whatever problems you
1768 have, let me (perlbug@perl.com) know how I blew it.
1770 This installation script affects things in two ways:
1772 1) it may do direct variable substitutions on some of the files included
1774 2) it builds a config.h file for inclusion in C programs. You may edit
1775 any of these files as the need arises after running this script.
1777 If you make a mistake on a question, there is no easy way to back up to it
1778 currently. The easiest thing to do is to edit config.sh and rerun all the SH
1779 files. Configure will offer to let you do this before it runs the SH files.

7095 Previous version of $package used the standard IO mechanisms as defined
7096 in <stdio.h>. Versions 5.003_02 and later of perl allow alternate IO
7097 mechanisms via a "PerlIO" abstraction, but the stdio mechanism is still
7098 the default. This abstraction layer can use AT&T's sfio (if you already
7099 have sfio installed) or regular stdio. Using PerlIO with sfio may cause
7100 problems with some extension modules. Using PerlIO with stdio is safe,
7101 but it is slower than plain stdio and therefore is not the default.
