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, I would
7# suggest you cut out the prototypical config.h from the end of Configure
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.)

517This installation shell script will examine your system and ask you questions
518to determine how the $package package should be installed. If you get stuck
519on a question, you may use a ! shell escape to start a subshell or execute
520a command. Many of the questions will have default answers in square
521brackets--typing carriage return will give you the default.
522
523On some of the questions which ask for file or directory names you are
524allowed to use the ~name construct to specify the login directory belonging
525to "name", even if you don't have a shell which knows about that. Questions
526where this is allowed will be marked "(~name ok)".

534Much effort has been expended to ensure that this shell script will run on any
535Unix system. If despite that it blows up on you, your best bet is to edit
536Configure and run it again. Also, let me (lwall@netlabs.com)
537know how I blew it. If you can't run Configure for some reason, you'll have
538to generate a config.sh file by hand.
539
540This installation script affects things in two ways: 1) it may do direct
541variable substitutions on some of the files included in this kit, and
5422) it builds a config.h file for inclusion in C programs. You may edit
543any of these files as the need arises after running this script.
544
545If you make a mistake on a question, there is no easy way to back up to it
546currently. The easiest thing to do is to edit config.sh and rerun all the
547SH files. Configure will offer to let you do this before it runs the SH files.

1503Some versions of Unix support shared libraries, which make
1504executables smaller but make load time slightly longer.
1505
1506On some systems, mostly newer Unix System V's, the shared library
1507is included by putting the option "-lc_s" as the last thing on the
1508cc command line when linking. Other systems use shared libraries
1509by default. There may be other libraries needed to compile $package
1510on your machine as well. If your system needs the "-lc_s" option,
1511include it here. Include any other special libraries here as well.
