Welcome to the easy install script.
I will ask you a few questions. Most of the time, a default value will
be printed, and you'll just need to hit the 'Return' key to confirm.
If you get stuck on a question, you may use a ! shell escape to start
a subshell or execute a !command.
Some questions asking for file or directory names allow the use of the ~user
construct to specify the login directory belonging to "user", even if you
don't have a shell which knows about that. They'll be marked "(~user ok)".
The prompter used in this script allows you to use shell variables and
backticks in your answers. You may use \$1, \$2, etc... to refer to the words
in the default answer, as if the default line was a set of arguments given to a
script shell. This means you may also use \$@ to repeat the whole default line,
so you do not have to re-type everything to add something to the default.
Everytime there is a substitution, you will have to confirm. If there is an
error (e.g. an unmatched backtick), the default answer will remain unchanged
and you will be prompted again.
If you are satisfied with your choices, I will then run a script for you
to work out some of the hairier parts of your system. Good luck!
