185 : general instructions
188 This installation shell script will examine your system and ask you questions
189 to determine how the $package package should be installed. If you get stuck
190 on a question, you may use a ! shell escape to start a subshell or execute
191 a command. Many of the questions will have default answers in square
192 brackets--typing carriage return will give you the default.
194 On some of the questions which ask for file or directory names you are
195 allowed to use the ~name construct to specify the login directory belonging
196 to "name", even if you don't have a shell which knows about that. Questions
197 where this is allowed will be marked "(~name ok)".
200 rp="[Type carriage return to continue]"
205 Much effort has been expended to ensure that this shell script will run
206 on any Unix system. If despite that it blows up on you, your best bet is
207 to edit Configure and run it again. Also, let me (lwall@jpl-devvax.jpl.nasa.gov)
208 know how I blew it. If you can't run Configure for some reason, you'll have
209 to generate a config.sh file by hand.
211 This installation script affects things in two ways: 1) it may do direct
212 variable substitutions on some of the files included in this kit, and
213 2) it builds a config.h file for inclusion in C programs. You may edit
214 any of these files as the need arises after running this script.
216 If you make a mistake on a question, there is no easy way to back up to it
217 currently. The easiest thing to do is to edit config.sh and rerun all the
218 SH files. Configure will offer to let you do this before it runs the SH files.
