184 | This installation shell script will examine your system and ask you questions |
185 | to determine how the $package package should be installed. If you get stuck |
186 | on a question, you may use a ! shell escape to start a subshell or execute |
187 | a command. Many of the questions will have default answers in square |
188 | brackets--typing carriage return will give you the default. |
189 | |
190 | On some of the questions which ask for file or directory names you are |
191 | allowed to use the ~name construct to specify the login directory belonging |
192 | to "name", even if you don't have a shell which knows about that. Questions |
193 | where this is allowed will be marked "(~name ok)". |

201 | Much effort has been expended to ensure that this shell script will run |
202 | on any Unix system. If despite that it blows up on you, your best bet is |
203 | to edit Configure and run it again. Also, let me (lwall@sdcrdcf.UUCP) know |
204 | how I blew it. If you can't run Configure for some reason, you'll have |
205 | to generate a config.sh file by hand. |
206 | |
207 | This installation script affects things in two ways: 1) it may do direct |
208 | variable substitutions on some of the files included in this kit, and |
209 | 2) it builds a config.h file for inclusion in C programs. You may edit |
210 | any of these files as the need arises after running this script. |
211 | |
212 | If you make a mistake on a question, there is no easy way to back up to it |
213 | currently. The easiest thing to do is to edit config.sh and rerun all the |
214 | SH files. Configure will offer to let you do this before it runs the SH files. |
