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.)
11 # Yes, you may rip this off to use in other distribution packages. This
12 # script belongs to the public domain and cannot be copyrighted.
14 # (Note: this Configure script was generated automatically. Rather than
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.)

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...]
39 OOPS! You naughty creature! You didn't run Configure with sh!

1536 This installation shell script will examine your system and ask you questions
1537 to determine how the perl5 package should be installed. If you get
1538 stuck on a question, you may use a ! shell escape to start a subshell or
1539 execute a command. Many of the questions will have default answers in square
1540 brackets; typing carriage return will give you the default.
1542 On some of the questions which ask for file or directory names you are allowed
1543 to use the ~name construct to specify the login directory belonging to "name",
1544 even if you don't have a shell which knows about that. Questions where this is
1545 allowed will be marked "(~name ok)".
1549 dflt='Type carriage return to continue'
1553 The prompter used in this script allows you to use shell variables and
1554 backticks in your answers. You may use $1, $2, etc... to refer to the words
1555 in the default answer, as if the default line was a set of arguments given to a
1556 script shell. This means you may also use $* to repeat the whole default line,
1557 so you do not have to re-type everything to add something to the default.
1559 Everytime there is a substitution, you will have to confirm. If there is an
1560 error (e.g. an unmatched backtick), the default answer will remain unchanged
1561 and you will be prompted again.
1563 If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all
1564 the questions and use the computed defaults (or the previous answers if there
1565 was already a config.sh file). Type 'Configure -h' for a list of options.
1566 You may also start interactively and then answer '& -d' at any prompt to turn
1567 on the non-interactive behaviour for the remainder of the execution.
1573 Much effort has been expended to ensure that this shell script will run on any
1574 Unix system. If despite that it blows up on yours, your best bet is to edit
1575 Configure and run it again. If you can't run Configure for some reason,
1576 you'll have to generate a config.sh file by hand. Whatever problems you
1577 have, let me (doughera@lafayette.edu) know how I blew it.
1579 This installation script affects things in two ways:
1581 1) it may do direct variable substitutions on some of the files included
1583 2) it builds a config.h file for inclusion in C programs. You may edit
1584 any of these files as the need arises after running this script.
1586 If you make a mistake on a question, there is no easy way to back up to it
1587 currently. The easiest thing to do is to edit config.sh and rerun all the SH
1588 files. Configure will offer to let you do this before it runs the SH files.

3749 Some versions of Unix support shared libraries, which make executables smaller
3750 but make load time slightly longer.
3752 On some systems, mostly System V Release 3's, the shared library is included
3753 by putting the option "-lc_s" as the last thing on the cc command line when
3754 linking. Other systems use shared libraries by default. There may be other
3755 libraries needed to compile $package on your machine as well. If your system
3756 needs the "-lc_s" option, include it here. Include any other special libraries
3757 here as well. Say "none" for none.
