16 # The dist-3.0 package (which contains metaconfig) was posted in

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.)

1328 This installation shell script will examine your system and ask you questions
1329 to determine how the perl5 package should be installed. If you get
1330 stuck on a question, you may use a ! shell escape to start a subshell or
1331 execute a command. Many of the questions will have default answers in square
1332 brackets; typing carriage return will give you the default.
1334 On some of the questions which ask for file or directory names you are allowed
1335 to use the ~name construct to specify the login directory belonging to "name",
1336 even if you don't have a shell which knows about that. Questions where this is
1337 allowed will be marked "(~name ok)".
1341 dflt='Type carriage return to continue'
1345 The prompter used in this script allows you to use shell variables and
1346 backticks in your answers. You may use $1, $2, etc... to refer to the words
1347 in the default answer, as if the default line was a set of arguments given to a
1348 script shell. This means you may also use $* to repeat the whole default line,
1349 so you do not have to re-type everything to add something to the default.
1351 Everytime there is a substitution, you will have to confirm. If there is an
1352 error (e.g. an unmatched backtick), the default answer will remain unchanged
1353 and you will be prompted again.
1355 If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all
1356 the questions and use the computed defaults (or the previous answers if there
1357 was already a config.sh file). Type 'Configure -h' for a list of options.
1358 You may also start interactively and then answer '& -d' at any prompt to turn
1359 on the non-interactive behaviour for the remaining of the execution.
1365 Much effort has been expended to ensure that this shell script will run on any
1366 Unix system. If despite that it blows up on yours, your best bet is to edit
1367 Configure and run it again. If you can't run Configure for some reason,
1368 you'll have to generate a config.sh file by hand. Whatever problems you
1369 have, let me (chip@atlantic.net) know how I blew it.
1371 This installation script affects things in two ways:
1373 1) it may do direct variable substitutions on some of the files included
1375 2) it builds a config.h file for inclusion in C programs. You may edit
1376 any of these files as the need arises after running this script.
1378 If you make a mistake on a question, there is no easy way to back up to it
1379 currently. The easiest thing to do is to edit config.sh and rerun all the SH
1380 files. Configure will offer to let you do this before it runs the SH files.

2575 If you decide to do so, you will be able to continue using any

2577 compatibility forces Perl to expose some of its internal symbols

3874 consuming task which may generate huge output on the disk (up to 3 megabytes)
