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.)

1336 This installation shell script will examine your system and ask you questions
1337 to determine how the perl5 package should be installed. If you get
1338 stuck on a question, you may use a ! shell escape to start a subshell or
1339 execute a command. Many of the questions will have default answers in square
1340 brackets; typing carriage return will give you the default.
1342 On some of the questions which ask for file or directory names you are allowed
1343 to use the ~name construct to specify the login directory belonging to "name",
1344 even if you don't have a shell which knows about that. Questions where this is
1345 allowed will be marked "(~name ok)".
1349 dflt='Type carriage return to continue'
1353 The prompter used in this script allows you to use shell variables and
1354 backticks in your answers. You may use $1, $2, etc... to refer to the words
1355 in the default answer, as if the default line was a set of arguments given to a
1356 script shell. This means you may also use $* to repeat the whole default line,
1357 so you do not have to re-type everything to add something to the default.
1359 Everytime there is a substitution, you will have to confirm. If there is an
1360 error (e.g. an unmatched backtick), the default answer will remain unchanged
1361 and you will be prompted again.
1363 If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all
1364 the questions and use the computed defaults (or the previous answers if there
1365 was already a config.sh file). Type 'Configure -h' for a list of options.
1366 You may also start interactively and then answer '& -d' at any prompt to turn
1367 on the non-interactive behavior for the remainder of the execution.
1373 Much effort has been expended to ensure that this shell script will run on any
1374 Unix system. If despite that it blows up on yours, your best bet is to edit
1375 Configure and run it again. If you can't run Configure for some reason,
1376 you'll have to generate a config.sh file by hand. Whatever problems you
1377 have, let me (chip@perl.com) know how I blew it.
1379 This installation script affects things in two ways:
1381 1) it may do direct variable substitutions on some of the files included
1383 2) it builds a config.h file for inclusion in C programs. You may edit
1384 any of these files as the need arises after running this script.
1386 If you make a mistake on a question, there is no easy way to back up to it
1387 currently. The easiest thing to do is to edit config.sh and rerun all the SH
1388 files. Configure will offer to let you do this before it runs the SH files.

4613 The perl executable is normally obtained by linking perlmain.c with
4614 libperl${lib_ext}, any static extensions (usually just DynaLoader), and
4615 any other libraries needed on this system (such as -lm, etc.). Since
4616 your system supports dynamic loading, it is probably possible to build
4617 a shared libperl.$so. If you will have more than one executable linked
4618 to libperl.$so, this will significantly reduce the size of each
4619 executable, but it may have a noticeable affect on performance. The
4620 default is probably sensible for your system.
