7 # I would suggest you have a look at the prototypical config_h.SH file
8 # and edit it to reflect your system. Some packages may include samples
9 # of config.h for certain machines, so you might look for one of those.)

15 # working with this copy of Configure, you may wish to get metaconfig.
16 # The dist-3.0 package (which contains metaconfig) was posted in
17 # comp.sources.misc and is available on CPAN under authors/id/RAM so
18 # you may fetch it yourself from your nearest archive site.)

28 SCO csh still thinks true is false. Write to SCO today and tell them that next
29 year Configure ought to "rm /bin/csh" unless they fix their blasted shell. :-)
31 (Actually, Configure ought to just patch csh in place. Hmm. Hmmmmm. All
32 we'd have to do is go in and swap the && and || tokens, wherever they are.)
34 [End of diatribe. We now return you to your regularly scheduled programming...]

1470 This installation shell script will examine your system and ask you questions
1471 to determine how the perl5 package should be installed. If you get
1472 stuck on a question, you may use a ! shell escape to start a subshell or
1473 execute a command. Many of the questions will have default answers in square
1474 brackets; typing carriage return will give you the default.
1476 On some of the questions which ask for file or directory names you are allowed
1477 to use the ~name construct to specify the login directory belonging to "name",
1478 even if you don't have a shell which knows about that. Questions where this is
1479 allowed will be marked "(~name ok)".
1483 dflt='Type carriage return to continue'
1487 The prompter used in this script allows you to use shell variables and
1488 backticks in your answers. You may use $1, $2, etc... to refer to the words
1489 in the default answer, as if the default line was a set of arguments given to a
1490 script shell. This means you may also use $* to repeat the whole default line,
1491 so you do not have to re-type everything to add something to the default.
1493 Everytime there is a substitution, you will have to confirm. If there is an
1494 error (e.g. an unmatched backtick), the default answer will remain unchanged
1495 and you will be prompted again.
1497 If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all
1498 the questions and use the computed defaults (or the previous answers if there
1499 was already a config.sh file). Type 'Configure -h' for a list of options.
1500 You may also start interactively and then answer '& -d' at any prompt to turn
1501 on the non-interactive behaviour for the remainder of the execution.
1507 Much effort has been expended to ensure that this shell script will run on any
1508 Unix system. If despite that it blows up on yours, your best bet is to edit
1509 Configure and run it again. If you can't run Configure for some reason,
1510 you'll have to generate a config.sh file by hand. Whatever problems you
1511 have, let me (doughera@lafcol.lafayette.edu) know how I blew it.
1513 This installation script affects things in two ways:
1515 1) it may do direct variable substitutions on some of the files included
1517 2) it builds a config.h file for inclusion in C programs. You may edit
1518 any of these files as the need arises after running this script.
1520 If you make a mistake on a question, there is no easy way to back up to it
1521 currently. The easiest thing to do is to edit config.sh and rerun all the SH
1522 files. Configure will offer to let you do this before it runs the SH files.

5757 Previous version of $package used the standard IO mechanisms as defined
5758 in <stdio.h>. Versions 5.003_02 and later of perl allow alternate IO
5759 mechanisms via a "PerlIO" abstraction, but the stdio mechanism is still
5760 the default. This abstraction layer can use AT&T's sfio (if you already
5761 have sfio installed) or regular stdio. Using PerlIO with sfio may cause
5762 problems with some extension modules. Using PerlIO with stdio is safe,
5763 but it is slower than plain stdio and therefore is not the default.
5765 If this doesn't make any sense to you, just accept the default 'n'.
