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.)

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.)

1241
1242	This installation shell script will examine your system and ask you questions
1243	to determine how the pennmush package should be installed. If you get
1244	stuck on a question, you may use a ! shell escape to start a subshell or
1245	execute a command. Many of the questions will have default answers in square
1246	brackets; typing carriage return will give you the default.
1247
1248	On some of the questions which ask for file or directory names you are allowed
1249	to use the ~name construct to specify the login directory belonging to "name",
1250	even if you don't have a shell which knows about that. Questions where this is
1251	allowed will be marked "(~name ok)".
1252

1257	cat <<'EOH'
1258
1259	The prompter used in this script allows you to use shell variables and
1260	backticks in your answers. You may use $1, $2, etc... to refer to the words
1261	in the default answer, as if the default line was a set of arguments given to a
1262	script shell. This means you may also use $* to repeat the whole default line,
1263	so you do not have to re-type everything to add something to the default.
1264
1265	Everytime there is a substitution, you will have to confirm. If there is an
1266	error (e.g. an unmatched backtick), the default answer will remain unchanged
1267	and you will be prompted again.
1268
1269	If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all
1270	the questions and use the computed defaults (or the previous answers if there
1271	was already a config.sh file). Type 'Configure -h' for a list of options.
1272	You may also start interactively and then answer '& -d' at any prompt to turn
1273	on the non-interactive behaviour for the remaining of the execution.

1278
1279	Much effort has been expended to ensure that this shell script will run on any
1280	Unix system. If despite that it blows up on yours, your best bet is to edit
1281	Configure and run it again. If you can't run Configure for some reason,
1282	you'll have to generate a config.sh file by hand. Whatever problems you
1283	have, let me (dunemush@pennmush.org) know how I blew it.
1284
1285	This installation script affects things in two ways:
1286
1287	1) it may do direct variable substitutions on some of the files included
1288	in this kit.
1289	2) it builds a config.h file for inclusion in C programs. You may edit
1290	any of these files as the need arises after running this script.
1291
1292	If you make a mistake on a question, there is no easy way to back up to it
1293	currently. The easiest thing to do is to edit config.sh and rerun all the SH
1294	files. Configure will offer to let you do this before it runs the SH files.
