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...]

1343 This installation shell script will examine your system and ask you questions
1344 to determine how the perl5 package should be installed. If you get
1345 stuck on a question, you may use a ! shell escape to start a subshell or
1346 execute a command. Many of the questions will have default answers in square
1347 brackets; typing carriage return will give you the default.
1349 On some of the questions which ask for file or directory names you are allowed
1350 to use the ~name construct to specify the login directory belonging to "name",
1351 even if you don't have a shell which knows about that. Questions where this is
1352 allowed will be marked "(~name ok)".
1356 dflt='Type carriage return to continue'
1360 The prompter used in this script allows you to use shell variables and
1361 backticks in your answers. You may use $1, $2, etc... to refer to the words
1362 in the default answer, as if the default line was a set of arguments given to a
1363 script shell. This means you may also use $* to repeat the whole default line,
1364 so you do not have to re-type everything to add something to the default.
1366 Everytime there is a substitution, you will have to confirm. If there is an
1367 error (e.g. an unmatched backtick), the default answer will remain unchanged
1368 and you will be prompted again.
1370 If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all
1371 the questions and use the computed defaults (or the previous answers if there
1372 was already a config.sh file). Type 'Configure -h' for a list of options.
1373 You may also start interactively and then answer '& -d' at any prompt to turn
1374 on the non-interactive behavior for the remainder of the execution.
1380 Much effort has been expended to ensure that this shell script will run on any
1381 Unix system. If despite that it blows up on yours, your best bet is to edit
1382 Configure and run it again. If you can't run Configure for some reason,
1383 you'll have to generate a config.sh file by hand. Whatever problems you
1384 have, let me (chip@perl.com) know how I blew it.
1386 This installation script affects things in two ways:
1388 1) it may do direct variable substitutions on some of the files included
1390 2) it builds a config.h file for inclusion in C programs. You may edit
1391 any of these files as the need arises after running this script.
1393 If you make a mistake on a question, there is no easy way to back up to it
1394 currently. The easiest thing to do is to edit config.sh and rerun all the SH
1395 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)
