# (If you are trying to port this package to a machine without sh, I would
# suggest you cut out the prototypical config.h from the end of Configure
# and edit it to reflect your system. Some packages may include samples
# of config.h for certain machines, so you might look for one of those.)

: general instructions
cat <
This installation shell script will examine your system and ask you questions
to determine how the $package package should be installed. If you get stuck
on a question, you may use a ! shell escape to start a subshell or execute
a command. Many of the questions will have default answers in square
brackets--typing carriage return will give you the default.

On some of the questions which ask for file or directory names you are
allowed to use the ~name construct to specify the login directory belonging
to "name", even if you don't have a shell which knows about that. Questions
where this is allowed will be marked "(~name ok)".

EOH

Much effort has been expended to ensure that this shell script will run
on any Unix system. If despite that it blows up on you, your best bet is
to edit Configure and run it again. Also, let me ([email protected])
know how I blew it. If you can't run Configure for some reason, you'll have
to generate a config.sh file by hand.

This installation script affects things in two ways: 1) it may do direct
variable substitutions on some of the files included in this kit, and
2) it builds a config.h file for inclusion in C programs. You may edit
any of these files as the need arises after running this script.

If you make a mistake on a question, there is no easy way to back up to it
currently. The easiest thing to do is to edit config.sh and rerun all the
SH files. Configure will offer to let you do this before it runs the SH files.

I'll have to use /bin/echo instead of the builtin, since Bourne shell doesn't

means I'll have to use $ans to suppress newlines now. Life is ridiculous.

Some systems have different model sizes. On most systems they are called
small, medium, large, and huge. On the PDP11 they are called unsplit and
split. If your system doesn't support different memory models, say "none".
If you wish to force everything to one memory model, say "none" here and
put the appropriate flags later when it asks you for other cc and ld flags.
Venix systems may wish to put "none" and let the compiler figure things out.
(In the following question multiple model names should be space separated.)

  1. Very nice! Thank you for this wonderful archive. I wonder why I found it only now. Long live the BBS file archives!

  2. This is so awesome! 😀 I’d be cool if you could download an entire archive of this at once, though.

  3. But one thing that puzzles me is the “mtswslnkmcjklsdlsbdmMICROSOFT” string. There is an article about it here. It is definitely worth a read: http://www.os2museum.com/wp/mtswslnk/
