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.)

1169 This installation shell script will examine your system and ask you questions
1170 to determine how the perl5 package should be installed. If you get
1171 stuck on a question, you may use a ! shell escape to start a subshell or
1172 execute a command. Many of the questions will have default answers in square
1173 brackets; typing carriage return will give you the default.
1175 On some of the questions which ask for file or directory names you are allowed
1176 to use the ~name construct to specify the login directory belonging to "name",
1177 even if you don't have a shell which knows about that. Questions where this is
1178 allowed will be marked "(~name ok)".
1182 dflt='Type carriage return to continue'
1186 The prompter used in this script allows you to use shell variables and
1187 backticks in your answers. You may use $1, $2, etc... to refer to the words
1188 in the default answer, as if the default line was a set of arguments given to a
1189 script shell. This means you may also use $* to repeat the whole default line,
1190 so you do not have to re-type everything to add something to the default.
1192 Everytime there is a substitution, you will have to confirm. If there is an
1193 error (e.g. an unmatched backtick), the default answer will remain unchanged
1194 and you will be prompted again.
1196 If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all
1197 the questions and use the computed defaults (or the previous answers if there
1198 was already a config.sh file). Type 'Configure -h' for a list of options.
1199 You may also start interactively and then answer '& -d' at any prompt to turn
1200 on the non-interactive behaviour for the remaining of the execution.
1206 Much effort has been expended to ensure that this shell script will run on any
1207 Unix system. If despite that it blows up on yours, your best bet is to edit
1208 Configure and run it again. If you can't run Configure for some reason,
1209 you'll have to generate a config.sh file by hand. Whatever problems you
1210 have, let me (lwall@netlabs.com) know how I blew it.
1212 This installation script affects things in two ways:
1214 1) it may do direct variable substitutions on some of the files included
1216 2) it builds a config.h file for inclusion in C programs. You may edit
1217 any of these files as the need arises after running this script.
1219 If you make a mistake on a question, there is no easy way to back up to it
1220 currently. The easiest thing to do is to edit config.sh and rerun all the SH
1221 files. Configure will offer to let you do this before it runs the SH files.
