16 # The dist-3.0 package (which contains metaconfig) was posted in
17 # comp.sources.misc so you may fetch it yourself from your nearest
18 # archive site. Check with Archie if you don't know where that can be.)

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.)

1170 This installation shell script will examine your system and ask you questions
1171 to determine how the perl5 package should be installed. If you get
1172 stuck on a question, you may use a ! shell escape to start a subshell or
1173 execute a command. Many of the questions will have default answers in square
1174 brackets; typing carriage return will give you the default.
1176 On some of the questions which ask for file or directory names you are allowed
1177 to use the ~name construct to specify the login directory belonging to "name",
1178 even if you don't have a shell which knows about that. Questions where this is
1179 allowed will be marked "(~name ok)".
1183 dflt='Type carriage return to continue'
1187 The prompter used in this script allows you to use shell variables and
1188 backticks in your answers. You may use $1, $2, etc... to refer to the words
1189 in the default answer, as if the default line was a set of arguments given to a
1190 script shell. This means you may also use $* to repeat the whole default line,
1191 so you do not have to re-type everything to add something to the default.
1193 Everytime there is a substitution, you will have to confirm. If there is an
1194 error (e.g. an unmatched backtick), the default answer will remain unchanged
1195 and you will be prompted again.
1197 If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all
1198 the questions and use the computed defaults (or the previous answers if there
1199 was already a config.sh file). Type 'Configure -h' for a list of options.
1200 You may also start interactively and then answer '& -d' at any prompt to turn
1201 on the non-interactive behaviour for the remaining of the execution.
1207 Much effort has been expended to ensure that this shell script will run on any
1208 Unix system. If despite that it blows up on yours, your best bet is to edit
1209 Configure and run it again. If you can't run Configure for some reason,
1210 you'll have to generate a config.sh file by hand. Whatever problems you
1211 have, let me (lwall@sems.com) know how I blew it.
1213 This installation script affects things in two ways:
1215 1) it may do direct variable substitutions on some of the files included
1217 2) it builds a config.h file for inclusion in C programs. You may edit
1218 any of these files as the need arises after running this script.
1220 If you make a mistake on a question, there is no easy way to back up to it
1221 currently. The easiest thing to do is to edit config.sh and rerun all the SH
1222 files. Configure will offer to let you do this before it runs the SH files.
