 * Configuration:
 
-Configure using 'make'.  This will ask you the location of the
-Linux kernel source tree.  If it detects that you have a kernel
-patched for RTAI or RTLinux, it will also ask you for the location
-of the RTAI or RTLinux source directory.  Then the configuration
-script will ask questions for a couple general Comedi features
-and then whether or not compile each driver.
+Configure with './configure'.  './configure --help' will give the
+configuration options.  If the configure script does not exist
+(if you checked comedi out from cvs for example), it can
+be generated by running './autogen.sh'.  The autoconf, automake,
+autoheader, etc. tools are required to generate the configure
+script (automake version >= 1.7 recommended).  The --with-linuxdir
+option is particularly useful, as it allows you to specify
+the location of your Linux kernel source directory.
