469 : general instructions
472 This installation shell script will examine your system and ask you questions
473 to determine how the $package package should be installed. If you get stuck
474 on a question, you may use a ! shell escape to start a subshell or execute
475 a command. Many of the questions will have default answers in square
476 brackets--typing carriage return will give you the default.
478 On some of the questions which ask for file or directory names you are
479 allowed to use the ~name construct to specify the login directory belonging
480 to "name", even if you don't have a shell which knows about that. Questions
481 where this is allowed will be marked "(~name ok)".
484 rp="[Type carriage return to continue]"
489 Much effort has been expended to ensure that this shell script will run on any
490 Unix system. If despite that it blows up on you, your best bet is to edit
491 Configure and run it again. Also, let me (lwall@jpl-devvax.jpl.nasa.gov)
492 know how I blew it. If you can't run Configure for some reason, you'll have
493 to generate a config.sh file by hand.
495 This installation script affects things in two ways: 1) it may do direct
496 variable substitutions on some of the files included in this kit, and
497 2) it builds a config.h file for inclusion in C programs. You may edit
498 any of these files as the need arises after running this script.
500 If you make a mistake on a question, there is no easy way to back up to it
501 currently. The easiest thing to do is to edit config.sh and rerun all the
502 SH files. Configure will offer to let you do this before it runs the SH files.
