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...]

1740 This installation shell script will examine your system and ask you questions
1741 to determine how the perl5 package should be installed. If you get
1742 stuck on a question, you may use a ! shell escape to start a subshell or
1743 execute a command. Many of the questions will have default answers in square
1744 brackets; typing carriage return will give you the default.
1746 On some of the questions which ask for file or directory names you are allowed
1747 to use the ~name construct to specify the login directory belonging to "name",
1748 even if you don't have a shell which knows about that. Questions where this is
1749 allowed will be marked "(~name ok)".
1753 dflt='Type carriage return to continue'
1757 The prompter used in this script allows you to use shell variables and
1758 backticks in your answers. You may use $1, $2, etc... to refer to the words
1759 in the default answer, as if the default line was a set of arguments given to a
1760 script shell. This means you may also use $* to repeat the whole default line,
1761 so you do not have to re-type everything to add something to the default.
1763 Everytime there is a substitution, you will have to confirm. If there is an
1764 error (e.g. an unmatched backtick), the default answer will remain unchanged
1765 and you will be prompted again.
1767 If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all
1768 the questions and use the computed defaults (or the previous answers if there
1769 was already a config.sh file). Type 'Configure -h' for a list of options.
1770 You may also start interactively and then answer '& -d' at any prompt to turn
1771 on the non-interactive behaviour for the remainder of the execution.
1777 Much effort has been expended to ensure that this shell script will run on any
1778 Unix system. If despite that it blows up on yours, your best bet is to edit
1779 Configure and run it again. If you can't run Configure for some reason,
1780 you'll have to generate a config.sh file by hand. Whatever problems you
1781 have, let me (perlbug@perl.com) know how I blew it.
1783 This installation script affects things in two ways:
1785 1) it may do direct variable substitutions on some of the files included
1787 2) it builds a config.h file for inclusion in C programs. You may edit
1788 any of these files as the need arises after running this script.
1790 If you make a mistake on a question, there is no easy way to back up to it
1791 currently. The easiest thing to do is to edit config.sh and rerun all the SH
1792 files. Configure will offer to let you do this before it runs the SH files.

7093 in <stdio.h>. Versions 5.003_02 and later of perl allow alternate IO
7094 mechanisms via a "PerlIO" abstraction, but the stdio mechanism is still
7095 the default. This abstraction layer can use AT&T's sfio (if you already
7096 have sfio installed) or regular stdio. Using PerlIO with sfio may cause
7097 problems with some extension modules. Using PerlIO with stdio is safe,
7098 but it is slower than plain stdio and therefore is not the default.
