 3. INSTALLATION::
+
      No installation is required. System-wide installation is not allowed
   for now.
 
 4. CONFIGURATION FILES::
-     Each book in the LFS series has its own set of configurable parameters
-  as well as the common parameters file.
 
      ::NEWS:: There is new configuration method for jhalfs.
 
      We have installed the familiar menu based configuration tool driven by
-     make. If you type the command
-       make
-     you will be presented with a list of configurable parameters (starting
-     with the book you wish to use). All the parameters found in the individual
-     config files are available. Once you have finished setting the parameters
-     and exit the make file will launch the chosen book version of jhalfs.
-     JHALFS will import your created file and overider the values found in normal
-     "config" files.
-     ..note.. The generated file <configuration> is only used by jhalfs if you
-     run jhalfs via make otherwise it is ignored.
+     by GNU make. see the section RUNNING, for details
 
-     If you want to try out the new configuration system without running jhalfs
-     issue the following.
-       make menuconfig
-     This will create a new file named configuration but will not launch jhalfs.
-
 5. RUNNING::
-     The script master.sh cannot be invoked directly but only via the
-  supplied symlinks. After editing the config file for the project you wish
-  to build, run the script.
 
-     IMPORTANT:
-       If you use the switch -M (automatically run the generated makefile) you
-       must be 'root' or you can run the scripts using 'sudo'
-        i.e.  sudo ./lfs -G -M
+     ::NEWS:: jhalfs is now launched via GNU make instead of individual symlinks.
+     The command <make> will launch a menu based configuration program. You will
+     recognize the layout from bulding the kernel or uClibc/Busybox. The
+     underlying menu code was borrowed from BusyBox and slightly modified for 
+     our use.
 
-       If you want to run make manually you can only do so if you are 'root' or
-       via 'sudo'
-        i.e  (from within the jhalfs directory) sudo make
+     Help on parameter function is available from the online help.
+     
+     Once you have set the parameters you wish and have saved your work the 
+     makefile will proceed to launch the jhalfs script. The script validate and
+     present you with your selections which you may accept or reject.
+     
+     If you accepted the displayed settings jhalfs will proceed to create the
+     makefile, optionally download packages.
 
-     The term <symlink> refers to the 1 of 3 package symlinks, lfs,hlfs,clfs.
-     Replace <symlink> with your choice of packages; i.e.: ./lfs
+     NOTE::    
+     If you run the jhalfs script directly the only funcion you can select is to
+     display the version number
 
-     ./<symlink>		eg: ./lfs or ./hlfs
-     Create a makefile based on the settings found in the config files.
-     You must enter the build partition/jhalfs directory and manually run <make>
 
-     ./<symlink> -G		eg: ./lfs -G
-     Download the packages and patches necessary to build <symlink>
-
-     ./<symlink> -G -M		eg: ./lfs -G -M
-     Download the packages, create and automatically run the Makefile
-
-     ./<symlink> --help		eg: ./lfs --help
-     will give you a context sensitive list of command line switches.

-   export SRC_ARCHIVE=/mnt/SourceFiles

-   explanation:::
-
-   export SRC_ARCHIVE=/mnt/SourceFiles
-      # This points to a local archive of existing packages. If the version in
-        the archive is incorrect jhalfs will access the net and download the
-	necessary version and store it here for later use. DO NOT set this to
-	$BUILDDIR/sources. If you do not set this variable to a valid directory
-	ALL package tarballs will be downloaded from the 'net.

-   -D /mnt/partition4
-      # where everything takes place.  ..NOTE it must already exist and be mounted

-   -K ~/jhalfs_configs/linux-2.6.16.19-LFS.config
-      # If you want to automatically build a the kernel you MUST supply a valid
-        kernel configuration file. The file you supply will be copied and renamed.
-
-   -F ~/jhalfs-configs/fstab-sda3
-      # If you have a fstab file you wish to use it will be copied and renamed
-
-   -G   # Retrieve the package files. You MUST enable this flag at least once if you
-          wish to do a build or whenever you update the book.

-   -T 0 # don't run any testsuites
