29 year Configure ought to "rm /bin/csh" unless they fix their blasted shell. :-)

32 we'd have to do is go in and swap the && and || tokens, wherever they are.)

1299 to determine how the perl5 package should be installed. If you get
1300 stuck on a question, you may use a ! shell escape to start a subshell or

1302 brackets; typing carriage return will give you the default.
1304 On some of the questions which ask for file or directory names you are allowed
1305 to use the ~name construct to specify the login directory belonging to "name",
1306 even if you don't have a shell which knows about that. Questions where this is
1307 allowed will be marked "(~name ok)".
1311 dflt='Type carriage return to continue'
1315 The prompter used in this script allows you to use shell variables and
1316 backticks in your answers. You may use $1, $2, etc... to refer to the words
1317 in the default answer, as if the default line was a set of arguments given to a
1318 script shell. This means you may also use $* to repeat the whole default line,
1319 so you do not have to re-type everything to add something to the default.
1321 Everytime there is a substitution, you will have to confirm. If there is an
1322 error (e.g. an unmatched backtick), the default answer will remain unchanged
1323 and you will be prompted again.
1325 If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all
1326 the questions and use the computed defaults (or the previous answers if there
1327 was already a config.sh file). Type 'Configure -h' for a list of options.
1328 You may also start interactively and then answer '& -d' at any prompt to turn
1329 on the non-interactive behaviour for the remaining of the execution.
1335 Much effort has been expended to ensure that this shell script will run on any
1336 Unix system. If despite that it blows up on yours, your best bet is to edit
1337 Configure and run it again. If you can't run Configure for some reason,
1338 you'll have to generate a config.sh file by hand. Whatever problems you
1339 have, let me (doughera@lafcol.lafayette.edu) know how I blew it.
1341 This installation script affects things in two ways:
1343 1) it may do direct variable substitutions on some of the files included
1345 2) it builds a config.h file for inclusion in C programs. You may edit
1346 any of these files as the need arises after running this script.
1348 If you make a mistake on a question, there is no easy way to back up to it
1349 currently. The easiest thing to do is to edit config.sh and rerun all the SH
1350 files. Configure will offer to let you do this before it runs the SH files.
