        HOW TO ADD CUSTOM SCRIPTS TO THE JHALFS MAKEFILE


  Normally JHALFS creates a Makefile containing only those scripts found in
the {B,C,H}LFS books. An automated construction tool cannot predict the
needs of every individual and requests are made "Can you add xxxx package".
Rather than adding numerous package scripts and switches for each request it
was easier to add a tool for the user(s) to code their own package needs.


  LAYOUT
  A new directory has been added to JHALFS tree which will contain the
configuration scripts and a few examples. A switch has been added to the
configuration file which enables/disables the inclusion of personal scripts.

    custom
      /config  <-- where to put your scripts.
      template <-- ALL scripts MUST look like this



  NOTE::: You are responsible for including all dependencies and ensuring they
          are built in the proper order.

  1. To add a package to the final JHALFS Makefile you must first create a file
     in the custom/config directory.
       **All config files MUST follow the naming convention, xxx-PKG, where xxx
       is the order number and PKG is the name of the package. The file naming
       format is important as it defines the build order. The example shown
       below has an order number 950 and log files will list in alphabetical
       order in the /logs directory after blfs-tools scripts.
    The simplest method is to copy the template file into the config directory
    and rename it.

  2. Populate the variables with the necessary values.
       Variable function is self explanitory except for the inclusion of the
       build cmds. If the package you want to include is found in the BLFS
       book then you only need to copy/paste the cmd strings between the xEOFx
       pairs, otherwise you will need to define the build cmds yourself.
     NOTE::: This script you just created is not usable directly but contains
             all the information necessary for jhalfs to create a build script
             and an entry in the jhalfs Makefile.

  3. As mentioned previously the build order is dictated by the 3 digit number
     in the file name. If a package has dependencies it must be numerically
     larger than the dependency files.
       ie. The package mc has glib as a dependency and build order is
           950-glib
           951-mc

  4. A config file for BLFS-bootscripts is already created as 999-blfs_bootscripts.
     If a package requires a bootscript to be installed add the cmd to this
     file and NOT in the package script. The gpm script is included as an
     example of multiple patch files and the need for a blfs bootscript.

  RUNNING:::
    Although your scripts are added to the generated makefile they are not
    automatically built. You must tell the makefile to build the tools with
    the cmd
        make mk_CUSTOM_TOOLS

  :::FINAL COMMENT:::
    This feature was added so users could build the packages necessary to access
    the internet and was not intended to replace the BLFS install system.


#--------- GLIB example -----------

  #
  # Filename syntax xxx-PKG  ie. 950-glibc
  # Create a file in the custom/config directory
  # Populate the file using the following script as an example
  #

PKG="glib"
PKG_VERSION="1.2.10"
PKG_FILE="glib-1.2.10.tar.gz"
URL="http://gd.tuwien.ac.at/graphics/gimp/gtk/v1.2/${PKG_FILE}"

  #  The convoluted scheme used to write out a temporary file is
