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.)

1308 This installation shell script will examine your system and ask you questions
1309 to determine how the perl5 package should be installed. If you get
1310 stuck on a question, you may use a ! shell escape to start a subshell or
1311 execute a command. Many of the questions will have default answers in square
1312 brackets; typing carriage return will give you the default.
1314 On some of the questions which ask for file or directory names you are allowed
1315 to use the ~name construct to specify the login directory belonging to "name",
1316 even if you don't have a shell which knows about that. Questions where this is
1317 allowed will be marked "(~name ok)".
1321 dflt='Type carriage return to continue'
1325 The prompter used in this script allows you to use shell variables and
1326 backticks in your answers. You may use $1, $2, etc... to refer to the words
1327 in the default answer, as if the default line was a set of arguments given to a
1328 script shell. This means you may also use $* to repeat the whole default line,
1329 so you do not have to re-type everything to add something to the default.
1331 Everytime there is a substitution, you will have to confirm. If there is an
1332 error (e.g. an unmatched backtick), the default answer will remain unchanged
1333 and you will be prompted again.
1335 If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all
1336 the questions and use the computed defaults (or the previous answers if there
1337 was already a config.sh file). Type 'Configure -h' for a list of options.
1338 You may also start interactively and then answer '& -d' at any prompt to turn
1339 on the non-interactive behaviour for the remaining of the execution.
1345 Much effort has been expended to ensure that this shell script will run on any
1346 Unix system. If despite that it blows up on yours, your best bet is to edit
1347 Configure and run it again. If you can't run Configure for some reason,
1348 you'll have to generate a config.sh file by hand. Whatever problems you
1349 have, let me (chip@atlantic.net) know how I blew it.
1351 This installation script affects things in two ways:
1353 1) it may do direct variable substitutions on some of the files included
1355 2) it builds a config.h file for inclusion in C programs. You may edit
1356 any of these files as the need arises after running this script.
1358 If you make a mistake on a question, there is no easy way to back up to it
1359 currently. The easiest thing to do is to edit config.sh and rerun all the SH
1360 files. Configure will offer to let you do this before it runs the SH files.

4618 I need to select a good name for the shared libperl. If your system uses
4619 library names with major and minor numbers, then you might want something
4620 like $majmin. Alternatively, if your system uses a single version
4621 number for shared libraries, then you might want to use $majonly.
4622 Or, your system might be quite happy with a simple libperl.$so.
4624 Since the shared libperl will get installed into a version-specific
4625 architecture-dependent directory, the version number of the shared perl
4626 library probably isn't important, so the default should be o.k.
