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.)

1356 This installation shell script will examine your system and ask you questions
1357 to determine how the perl5 package should be installed. If you get
1358 stuck on a question, you may use a ! shell escape to start a subshell or
1359 execute a command. Many of the questions will have default answers in square
1360 brackets; typing carriage return will give you the default.
1362 On some of the questions which ask for file or directory names you are allowed
1363 to use the ~name construct to specify the login directory belonging to "name",
1364 even if you don't have a shell which knows about that. Questions where this is
1365 allowed will be marked "(~name ok)".
1369 dflt='Type carriage return to continue'
1373 The prompter used in this script allows you to use shell variables and
1374 backticks in your answers. You may use $1, $2, etc... to refer to the words
1375 in the default answer, as if the default line was a set of arguments given to a
1376 script shell. This means you may also use $* to repeat the whole default line,
1377 so you do not have to re-type everything to add something to the default.
1379 Everytime there is a substitution, you will have to confirm. If there is an
1380 error (e.g. an unmatched backtick), the default answer will remain unchanged
1381 and you will be prompted again.
1383 If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all
1384 the questions and use the computed defaults (or the previous answers if there
1385 was already a config.sh file). Type 'Configure -h' for a list of options.
1386 You may also start interactively and then answer '& -d' at any prompt to turn
1387 on the non-interactive behavior for the remainder of the execution.
1393 Much effort has been expended to ensure that this shell script will run on any
1394 Unix system. If despite that it blows up on yours, your best bet is to edit
1395 Configure and run it again. If you can't run Configure for some reason,
1396 you'll have to generate a config.sh file by hand. Whatever problems you
1397 have, let me (chip@perl.com) know how I blew it.
1399 This installation script affects things in two ways:
1401 1) it may do direct variable substitutions on some of the files included
1403 2) it builds a config.h file for inclusion in C programs. You may edit
1404 any of these files as the need arises after running this script.
1406 If you make a mistake on a question, there is no easy way to back up to it
1407 currently. The easiest thing to do is to edit config.sh and rerun all the SH
1408 files. Configure will offer to let you do this before it runs the SH files.

3905 consuming task which may generate huge output on the disk (up to 3 megabytes)

4625 The perl executable is normally obtained by linking perlmain.c with
4626 libperl${lib_ext}, any static extensions (usually just DynaLoader), and
4627 any other libraries needed on this system (such as -lm, etc.). Since
4628 your system supports dynamic loading, it is probably possible to build
4629 a shared libperl.$so. If you will have more than one executable linked
4630 to libperl.$so, this will significantly reduce the size of each
4631 executable, but it may have a noticeable affect on performance. The
4632 default is probably sensible for your system.

4701 I need to select a good name for the shared libperl. If your system uses
4702 library names with major and minor numbers, then you might want something
4703 like $majmin. Alternatively, if your system uses a single version
4704 number for shared libraries, then you might want to use $majonly.
4705 Or, your system might be quite happy with a simple libperl.$so.
4707 Since the shared libperl will get installed into a version-specific
4708 architecture-dependent directory, the version number of the shared perl
4709 library probably isn't important, so the default should be o.k.
