3	# If these # comments don't work, trim them. Don't worry about any other
4	# shell scripts, Configure will trim # comments from them for you.

6	# (If you are trying to port this package to a machine without sh,
7	# I would suggest you have a look at the prototypical config_h.SH file
8	# and edit it to reflect your system. Some packages may include samples
9	# of config.h for certain machines, so you might look for one of those.)
10	#
11	# Yes, you may rip this off to use in other distribution packages. This
12	# script belongs to the public domain and cannot be copyrighted.
13	#
14	# (Note: this Configure script was generated automatically. Rather than
15	# working with this copy of Configure, you may wish to get metaconfig.
16	# The dist-3.0 package (which contains metaconfig) was posted in
17	# comp.sources.misc and is available on CPAN under authors/id/RAM so
18	# you may fetch it yourself from your nearest archive site.)

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. :-)
30
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.)

1246
1247	This installation shell script will examine your system and ask you questions
1248	to determine how the pennmush package should be installed. If you get
1249	stuck on a question, you may use a ! shell escape to start a subshell or
1250	execute a command. Many of the questions will have default answers in square
1251	brackets; typing carriage return will give you the default.
1252
1253	On some of the questions which ask for file or directory names you are allowed
1254	to use the ~name construct to specify the login directory belonging to "name",
1255	even if you don't have a shell which knows about that. Questions where this is
1256	allowed will be marked "(~name ok)".
1257

1262	cat <<'EOH'
1263
1264	The prompter used in this script allows you to use shell variables and
1265	backticks in your answers. You may use $1, $2, etc... to refer to the words
1266	in the default answer, as if the default line was a set of arguments given to a
1267	script shell. This means you may also use $* to repeat the whole default line,
1268	so you do not have to re-type everything to add something to the default.
1269
1270	Everytime there is a substitution, you will have to confirm. If there is an
1271	error (e.g. an unmatched backtick), the default answer will remain unchanged
1272	and you will be prompted again.
1273
1274	If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all
1275	the questions and use the computed defaults (or the previous answers if there
1276	was already a config.sh file). Type 'Configure -h' for a list of options.
1277	You may also start interactively and then answer '& -d' at any prompt to turn
1278	on the non-interactive behaviour for the remaining of the execution.

1283
1284	Much effort has been expended to ensure that this shell script will run on any
1285	Unix system. If despite that it blows up on yours, your best bet is to edit
1286	Configure and run it again. If you can't run Configure for some reason,
1287	you'll have to generate a config.sh file by hand. Whatever problems you
1288	have, let me (pennmush-developers@pennmush.org) know how I blew it.
1289
1290	This installation script affects things in two ways:
1291
1292	1) it may do direct variable substitutions on some of the files included
1293	in this kit.
1294	2) it builds a config.h file for inclusion in C programs. You may edit
1295	any of these files as the need arises after running this script.
1296
1297	If you make a mistake on a question, there is no easy way to back up to it
1298	currently. The easiest thing to do is to edit config.sh and rerun all the SH
1299	files. Configure will offer to let you do this before it runs the SH files.
