# Revision:
#  Removed unsigned long declarations from random number tester,
#  8/26/87, for pdp-11's and the 2.10 release.  Also fixed bug with
#  grep and the search for '-i' using $contains, and changed the man
#  directory for the search to /usr/man/man1.  Then fixed the man
#  installation suffix to be .6 if necessary.
#
# If these # comments don't work, trim them.  Don't worry about any other
# shell scripts, Configure will trim # comments from them for you.
#
# (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.)
#
# $Header: Configure,v 1.1 87/08/26 03:37:30 cr Exp $
#
# Yes, you may rip this off to use in other distribution packages.
# (Note: this Configure script was generated automatically.  Rather than
# working with this copy of Configure, you may wish to get metaconfig.)

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)".

cat <<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 (lwall@sdcrdcf.UUCP) 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.

They are not compatible!  You are probably running ksh on a non-USG system.
I'll have to use /bin/echo instead of the builtin, since Bourne shell doesn't
have echo built in and we may have to run some Bourne shell scripts.  That
means I'll have to use $ans to suppress newlines now.  Life is ridiculous.

I can set things up so that your shell scripts and binaries are more portable,
at what may be a noticable cost in performance.  In particular, if you
ask to be portable, the following happens:

     1) shell scripts will rely on the PATH variable rather than using
	the paths derived above.
     2) ~username interpretations will be done at run time rather than

possibilities at this point:

1)  You can have your host name ($hostname) compiled into $package, which

2)  you can have $package use a

Option 1 will give you the option of using whoami.h if you have one.  If you

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.)

If you do a make install as the superuser, I can chown all the publicly
visible files to be owned by some particular user id.  Any setuid programs
in this package will run under this uid, and be able to access the files
that belong to this uid.  You should pick a uid that nobody can log into
that you don't trust to modify the programs or data files of this package.
You should probably not pick root if there are any setuid programs in this
package.  If you want to create a uid for this, do so before the make install.

NOTE: the V7 compiler may ignore some #undefs that $package uses.  If so,
you may get messages about redefining EXT.  Some V7 compilers also have
difficulties with #defines near buffer boundaries, so beware.  You may have
to play with the spacing in some .h files, believe it or not.

may not work as well as it might.  It might not work at all.
