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...]

1459 This installation shell script will examine your system and ask you questions
1460 to determine how the perl5 package should be installed. If you get
1461 stuck on a question, you may use a ! shell escape to start a subshell or
1462 execute a command. Many of the questions will have default answers in square
1463 brackets; typing carriage return will give you the default.
1465 On some of the questions which ask for file or directory names you are allowed
1466 to use the ~name construct to specify the login directory belonging to "name",
1467 even if you don't have a shell which knows about that. Questions where this is
1468 allowed will be marked "(~name ok)".
1472 dflt='Type carriage return to continue'
1476 The prompter used in this script allows you to use shell variables and
1477 backticks in your answers. You may use $1, $2, etc... to refer to the words
1478 in the default answer, as if the default line was a set of arguments given to a
1479 script shell. This means you may also use $* to repeat the whole default line,
1480 so you do not have to re-type everything to add something to the default.
1482 Everytime there is a substitution, you will have to confirm. If there is an
1483 error (e.g. an unmatched backtick), the default answer will remain unchanged
1484 and you will be prompted again.
1486 If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all
1487 the questions and use the computed defaults (or the previous answers if there
1488 was already a config.sh file). Type 'Configure -h' for a list of options.
1489 You may also start interactively and then answer '& -d' at any prompt to turn
1490 on the non-interactive behaviour for the remainder of the execution.
1496 Much effort has been expended to ensure that this shell script will run on any
1497 Unix system. If despite that it blows up on yours, your best bet is to edit
1498 Configure and run it again. If you can't run Configure for some reason,
1499 you'll have to generate a config.sh file by hand. Whatever problems you
1500 have, let me (doughera@lafcol.lafayette.edu) know how I blew it.
1502 This installation script affects things in two ways:
1504 1) it may do direct variable substitutions on some of the files included
1506 2) it builds a config.h file for inclusion in C programs. You may edit
1507 any of these files as the need arises after running this script.
1509 If you make a mistake on a question, there is no easy way to back up to it
1510 currently. The easiest thing to do is to edit config.sh and rerun all the SH
1511 files. Configure will offer to let you do this before it runs the SH files.

3900 Some versions of Unix support shared libraries, which make executables smaller
3901 but make load time slightly longer.
3903 On some systems, mostly System V Release 3's, the shared library is included
3904 by putting the option "-lc_s" as the last thing on the cc command line when
3905 linking. Other systems use shared libraries by default. There may be other
3906 libraries needed to compile $package on your machine as well. If your system
3907 needs the "-lc_s" option, include it here. Include any other special libraries
3908 here as well. Say "none" for none.
