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...]

1435 This installation shell script will examine your system and ask you questions
1436 to determine how the perl5 package should be installed. If you get
1437 stuck on a question, you may use a ! shell escape to start a subshell or
1438 execute a command. Many of the questions will have default answers in square
1439 brackets; typing carriage return will give you the default.
1441 On some of the questions which ask for file or directory names you are allowed
1442 to use the ~name construct to specify the login directory belonging to "name",
1443 even if you don't have a shell which knows about that. Questions where this is
1444 allowed will be marked "(~name ok)".
1448 dflt='Type carriage return to continue'
1452 The prompter used in this script allows you to use shell variables and
1453 backticks in your answers. You may use $1, $2, etc... to refer to the words
1454 in the default answer, as if the default line was a set of arguments given to a
1455 script shell. This means you may also use $* to repeat the whole default line,
1456 so you do not have to re-type everything to add something to the default.
1458 Everytime there is a substitution, you will have to confirm. If there is an
1459 error (e.g. an unmatched backtick), the default answer will remain unchanged
1460 and you will be prompted again.
1462 If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all
1463 the questions and use the computed defaults (or the previous answers if there
1464 was already a config.sh file). Type 'Configure -h' for a list of options.
1465 You may also start interactively and then answer '& -d' at any prompt to turn
1466 on the non-interactive behaviour for the remainder of the execution.
1472 Much effort has been expended to ensure that this shell script will run on any
1473 Unix system. If despite that it blows up on yours, your best bet is to edit
1474 Configure and run it again. If you can't run Configure for some reason,
1475 you'll have to generate a config.sh file by hand. Whatever problems you
1476 have, let me (doughera@lafcol.lafayette.edu) know how I blew it.
1478 This installation script affects things in two ways:
1480 1) it may do direct variable substitutions on some of the files included
1482 2) it builds a config.h file for inclusion in C programs. You may edit
1483 any of these files as the need arises after running this script.
1485 If you make a mistake on a question, there is no easy way to back up to it
1486 currently. The easiest thing to do is to edit config.sh and rerun all the SH
1487 files. Configure will offer to let you do this before it runs the SH files.
