   Configuration
 
-   There are several configuration variables that can be set. The
-   default values are kept in the file `Variables'.
-
-   Variables is in the format `VAR_NAME<tab>VALUE'. You can modify
-   these configuration variables by editing the `Variables' file

    	$ ./configure --VAR_NAME=VALUE
 
    The different configuration variables are as follows:
-   VER   	value='0.6.3'
-   	rvs's internal varsion number
-   SHELL 	value='/usr/bin/env bash'
-   	the shell that scripts will be run in.
-   prefix	value="$HOME"
-   	where the files will be installed. For me the defualt is
-   	`/home/luke'. Many of you will want to change this to '/usr'
-   bindir	value='bin'
-   	the binaries folder inside the prefix. If I leave the prefix
-   	and bindir the same, for me rvs is installed in
-   	`/home/luke/bin'. If I change prefix to '/usr', then rvs will
-   	be installed in `/usr/bin'
-   libdir	value='/etc/rvs/'
-   	where the rvs libraries will be installed. In rvs almost
-   	nothing is actually done in the execurable you call when you
-   	type `rvs' ([$prefix]/[$bindir]/rvs) but option handling. All
-   	the real work is done in modular sub-programs. I call them
-   	libraries, even though they are independend programs that
-   	communicate via pipes.  Note that they probably should NOT be
-   	located in your PATH.
+   	name='rvs'
+   		The name of the program. Note that unlike most
+   		variables, you should NOT call this in Makefiles
+   		(`$(name)'), but use $(rvs) instead.
+   	RVS='$(bindir)/$(rvs)'
+   		Where the exectuable will be. `$(rvs)' is the same as
+   		`$(name)' (see above)
+   	SHELL='/bin/sh'
+   		The shell that will be used by make, and the shell
+   		that scripts will run in. (Perhaps we should make
+   		these separate variables?)
+   	prefix='/usr/local'
+   		Standard GNU variable. Many of you will want to
+   		change this to `/usr', or `/home/USER_NAME'
+   	exec_prefix='$(prefix)'
+   		Standard GNU variable.
+   	bindir='$(exec_prefix)/bin'
+   		Standard GNU variable.
+   	sbindir='$(exec_prefix)/sbin'
+   		Standard GNU variable.
+   	libexecdir='$(exec_prefix)/libexec'
+   		Standard GNU variable.  The plugins will be installed
+   		at $(libexecdir)/$(name)
+   	srcdir=$(readlink -f `dirname "$0"`)
+   		Where the source code is.  The default value evaluates
+   		to the directory of the `configure' script.
