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...]

1349 This installation shell script will examine your system and ask you questions
1350 to determine how the perl5 package should be installed. If you get
1351 stuck on a question, you may use a ! shell escape to start a subshell or
1352 execute a command. Many of the questions will have default answers in square
1353 brackets; typing carriage return will give you the default.
1355 On some of the questions which ask for file or directory names you are allowed
1356 to use the ~name construct to specify the login directory belonging to "name",
1357 even if you don't have a shell which knows about that. Questions where this is
1358 allowed will be marked "(~name ok)".
1362 dflt='Type carriage return to continue'
1366 The prompter used in this script allows you to use shell variables and
1367 backticks in your answers. You may use $1, $2, etc... to refer to the words
1368 in the default answer, as if the default line was a set of arguments given to a
1369 script shell. This means you may also use $* to repeat the whole default line,
1370 so you do not have to re-type everything to add something to the default.
1372 Everytime there is a substitution, you will have to confirm. If there is an
1373 error (e.g. an unmatched backtick), the default answer will remain unchanged
1374 and you will be prompted again.
1376 If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all
1377 the questions and use the computed defaults (or the previous answers if there
1378 was already a config.sh file). Type 'Configure -h' for a list of options.
1379 You may also start interactively and then answer '& -d' at any prompt to turn
1380 on the non-interactive behavior for the remainder of the execution.
1386 Much effort has been expended to ensure that this shell script will run on any
1387 Unix system. If despite that it blows up on yours, your best bet is to edit
1388 Configure and run it again. If you can't run Configure for some reason,
1389 you'll have to generate a config.sh file by hand. Whatever problems you
1390 have, let me (chip@perl.com) know how I blew it.
1392 This installation script affects things in two ways:
1394 1) it may do direct variable substitutions on some of the files included
1396 2) it builds a config.h file for inclusion in C programs. You may edit
1397 any of these files as the need arises after running this script.
1399 If you make a mistake on a question, there is no easy way to back up to it
1400 currently. The easiest thing to do is to edit config.sh and rerun all the SH
1401 files. Configure will offer to let you do this before it runs the SH files.

4618 The perl executable is normally obtained by linking perlmain.c with
4619 libperl${lib_ext}, any static extensions (usually just DynaLoader), and
4620 any other libraries needed on this system (such as -lm, etc.). Since
4621 your system supports dynamic loading, it is probably possible to build
4622 a shared libperl.$so. If you will have more than one executable linked
4623 to libperl.$so, this will significantly reduce the size of each
4624 executable, but it may have a noticeable affect on performance. The
4625 default is probably sensible for your system.
