6 # (If you are trying to port this package to a machine without sh,
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...]

1486 This installation shell script will examine your system and ask you questions
1487 to determine how the perl5 package should be installed. If you get
1488 stuck on a question, you may use a ! shell escape to start a subshell or
1489 execute a command. Many of the questions will have default answers in square
1490 brackets; typing carriage return will give you the default.
1492 On some of the questions which ask for file or directory names you are allowed
1493 to use the ~name construct to specify the login directory belonging to "name",
1494 even if you don't have a shell which knows about that. Questions where this is
1495 allowed will be marked "(~name ok)".
1499 dflt='Type carriage return to continue'
1503 The prompter used in this script allows you to use shell variables and
1504 backticks in your answers. You may use $1, $2, etc... to refer to the words
1505 in the default answer, as if the default line was a set of arguments given to a
1506 script shell. This means you may also use $* to repeat the whole default line,
1507 so you do not have to re-type everything to add something to the default.
1509 Everytime there is a substitution, you will have to confirm. If there is an
1510 error (e.g. an unmatched backtick), the default answer will remain unchanged
1511 and you will be prompted again.
1513 If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all
1514 the questions and use the computed defaults (or the previous answers if there
1515 was already a config.sh file). Type 'Configure -h' for a list of options.
1516 You may also start interactively and then answer '& -d' at any prompt to turn
1517 on the non-interactive behaviour for the remainder of the execution.
1523 Much effort has been expended to ensure that this shell script will run on any
1524 Unix system. If despite that it blows up on yours, your best bet is to edit
1525 Configure and run it again. If you can't run Configure for some reason,
1526 you'll have to generate a config.sh file by hand. Whatever problems you
1527 have, let me (doughera@lafcol.lafayette.edu) know how I blew it.
1529 This installation script affects things in two ways:
1531 1) it may do direct variable substitutions on some of the files included
1533 2) it builds a config.h file for inclusion in C programs. You may edit
1534 any of these files as the need arises after running this script.
1536 If you make a mistake on a question, there is no easy way to back up to it
1537 currently. The easiest thing to do is to edit config.sh and rerun all the SH
1538 files. Configure will offer to let you do this before it runs the SH files.

5777 Previous version of $package used the standard IO mechanisms as defined
5778 in <stdio.h>. Versions 5.003_02 and later of perl allow alternate IO
5779 mechanisms via a "PerlIO" abstraction, but the stdio mechanism is still
5780 the default. This abstraction layer can use AT&T's sfio (if you already
5781 have sfio installed) or regular stdio. Using PerlIO with sfio may cause
5782 problems with some extension modules. Using PerlIO with stdio is safe,
5783 but it is slower than plain stdio and therefore is not the default.
5785 If this doesn't make any sense to you, just accept the default 'n'.
