# unshar, or by typing "sh <file", e.g..  If this archive is complete, you

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

X# (If you are trying to port this package to a machine without sh,
X# I would suggest you have a look at the prototypical config.h.SH file
X# and edit it to reflect your system. Some packages may include samples
X# of config.h for certain machines, so you might look for one of those.)
X#
X# Yes, you may rip this off to use in other distribution packages. This
X# script belongs to the public domain and cannot be copyrighted.
X#
X# (Note: this Configure script was generated automatically. Rather than
X# working with this copy of Configure, you may wish to get metaconfig.
X# The dist-3.0 package (which contains metaconfig) was posted in
X# comp.sources.misc so you may fetch it yourself from your nearest
X# archive site. Check with Archie if you don't know where that can be.)

XSCO csh still thinks true is false.  Write to SCO today and tell them that next
Xyear Configure ought to "rm /bin/csh" unless they fix their blasted shell. :-)

Xwe'd have to do is go in and swap the && and || tokens, wherever they are.)

XThis installation shell script will examine your system and ask you questions
Xto determine how the mthreads package should be installed. If you get
Xstuck on a question, you may use a ! shell escape to start a subshell or
Xexecute a command.  Many of the questions will have default answers in square
Xbrackets; typing carriage return will give you the default.
X
XOn some of the questions which ask for file or directory names you are allowed
Xto use the ~name construct to specify the login directory belonging to "name",
Xeven if you don't have a shell which knows about that.  Questions where this is
Xallowed will be marked "(~name ok)".

X
XThe prompter used in this script allows you to use shell variables and
Xbackticks in your answers.  You may use $1, $2, etc...  to refer to the words
Xin the default answer, as if the default line was a set of arguments given to a
Xscript shell.  This means you may also use $* to repeat the whole default line,
Xso you do not have to re-type everything to add something to the default.
X
XEverytime there is a substitution, you will have to confirm.  If there is an
Xerror (e.g. an unmatched backtick), the default answer will remain unchanged
Xand you will be prompted again.
X
XIf you are in a hurry, you may run 'Configure -d'.  This will bypass nearly all
Xthe questions and use the computed defaults (or the previous answers if there
Xwas already a config.sh file). Type 'Configure -h' for a list of options.

XMuch effort has been expended to ensure that this shell script will run on any

XConfigure and run it again.  Also, let me ([e-mail])
Xknow how I blew it.  If you can't run Configure for some reason, you'll have to
Xgenerate a config.sh file by hand.
X
XThis installation script affects things in two ways:
X
X1) it may do direct variable substitutions on some of the files included
X   in this kit.
X2) it builds a config.h file for inclusion in C programs.  You may edit
X   any of these files as the need arises after running this script.
X
XIf you make a mistake on a question, there is no easy way to back up to it
Xcurrently.  The easiest thing to do is to edit config.sh and rerun all the SH
Xfiles.  Configure will offer to let you do this before it runs the SH files.
