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.)

1298 to determine how the perl5 package should be installed. If you get
1299 stuck on a question, you may use a ! shell escape to start a subshell or
1300 execute a command. Many of the questions will have default answers in square
1301 brackets; typing carriage return will give you the default.
1303 On some of the questions which ask for file or directory names you are allowed
1304 to use the ~name construct to specify the login directory belonging to "name",
1305 even if you don't have a shell which knows about that. Questions where this is
1306 allowed will be marked "(~name ok)".

1314 The prompter used in this script allows you to use shell variables and
1315 backticks in your answers. You may use $1, $2, etc... to refer to the words
1316 in the default answer, as if the default line was a set of arguments given to a
1317 script shell. This means you may also use $* to repeat the whole default line,
1318 so you do not have to re-type everything to add something to the default.
1320 Everytime there is a substitution, you will have to confirm. If there is an
1321 error (e.g. an unmatched backtick), the default answer will remain unchanged
1322 and you will be prompted again.
1324 If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all
1325 the questions and use the computed defaults (or the previous answers if there
1326 was already a config.sh file). Type 'Configure -h' for a list of options.
1327 You may also start interactively and then answer '& -d' at any prompt to turn
1328 on the non-interactive behaviour for the remaining of the execution.
1334 Much effort has been expended to ensure that this shell script will run on any
1335 Unix system. If despite that it blows up on yours, your best bet is to edit
1336 Configure and run it again. If you can't run Configure for some reason,
1337 you'll have to generate a config.sh file by hand. Whatever problems you
1338 have, let me (doughera@lafcol.lafayette.edu) know how I blew it.
1340 This installation script affects things in two ways:
1342 1) it may do direct variable substitutions on some of the files included
1344 2) it builds a config.h file for inclusion in C programs. You may edit
1345 any of these files as the need arises after running this script.
1347 If you make a mistake on a question, there is no easy way to back up to it
1348 currently. The easiest thing to do is to edit config.sh and rerun all the SH
1349 files. Configure will offer to let you do this before it runs the SH files.
