	where <default> is the default directory of the base
	RPMS.  In our case that will be HEPL.

	  /HEPL/RPMS/ 

	where <sitename> is your sitename which is the directory			under sites/ . 

	In this example it will be "example" 

	  /sites/example/
			
        where <tree> is the directory where <default>/ exists
		
	In this example it is /mnt/src/hepl30rolling/i386/
	Note that it must be a full path name. 
 	 
------------------------------------------------------------------------------
Steps for making your own site customization
------------------------------------------------------------------------------
In this example we will call our new site "newsite" so $SITE is "newsite".
The <tree> is in /mnt/src/hepl30rolling/i386/ and is defined as $TREE
and <default> is HEPL and is defined as $DEFAULT

DEFAULT=HEPL
SITE=newsite 
TREE=/mnt/src/hepl30rolling/i386/
cd $TREE
mkdir sites/newsite			  # Create new site area
cd sites/example
find . -print | cpio -pvdum ../newsite    # copy over example area as a start
cd ../newsite/Updates

  <add and remove RPMS in "Updates" to customize as you want, 
  For the rpms you want to change install the SRPM and then make changes
  as necessary in /usr/src/redhat/SPECS/ .  You should change the version
  string so as to distinguish it from the original.

  Some rpms that you might want to change are

     yum-conf 

	so to point to your local yum repository 

     example-release 

	to contain your own release name.  This will change the name of this
        rpm and will require you to change the example-release entry in 
        ../base/comps* so the installer will find the right rpm> 

     anaconda-images

	This rpm contains the graphics used during the install.  See 
        README.images for info on what could/should be changed.
    
     anaconda-help

	This rpm contains the "help" info on the left side of the gui installer
	screen.  You might want to change the "HEPL" to be your site name.

cd ../base

  <modify "comps.xml.main" to include added RPMS and other site
  customizations, The one included here is the same as what is in HEPL itself,
  with hepl-release changed to example-release>

sh cp.comps.xml.main.sh 
cd -

  <modify files in "build/isolinux" as described in "build/isolinux/README"
   NOTE that this is <tree>/sites/$SITE/build/isolinux and NOT 
   <tree>/isolinux/ >

cd build/scripts

  <modify locations.include to fix TREE= and SITE= to be 
  TREE=<where ever your tree is located>  # In our case it is already ok.
  SITE=newsite
  change --product string in build.release.example.sh>

sh make.updates.example.sh     # Need to do whenever you change contents of
			       # $TREE/sites/$SITE/RHupdates/

sh build.hdlist.example.sh     # Run this whenever you change contents of
			       # $TREE/sites/$SITE/Updates/

sh build.release.example.sh    # Only need to run this when changing installer
			       # kernel , but at least 1 time

<now test install with images in "$TREE/sites/$SITE/images/">



while <notdone>

   <add and remove RPMS in "$TREE/sites/$SITE/Updates" to customize as you want>

   <run $TREE/sites/$SITE/build/scripts/build.hdlist.example.sh after each 
    batch of changes>

   <modify $TREE/sites/$SITE/base/comps.xml.main and run 
   $TREE/sites/$SITE/base/scripts/cp.comps.xml.main.sh when you want to move
   these changes over as your "real comps.xml">

   <test with install images in $TREE/sites/$SITE/images/, only need to 
   rebuild these when installer kernel changes or anaconda rpms change 
   and you want to include those changes
   Note that anaconda python changes can be placed in 
   $TREE/sites/$SITE/RHupdates/ , this makes testing easier,  they do
   NOT have to be put in the anaconda rpms unless that is what you want>
