'''1. Adding license in Server Side :'''
[[BR]]
     * In order to add a license for a especific package, you need to create a .txt license file under path of a directory of package on
       [http://download.osgeo.org/osgeo4w] server, for example:
        {{{ 
         svn someuser@download.osgeo.org   # log in into server 

         cd osgeo/download/osgeo4w/release/gdal/gdal-ecw

         touch gdal-ecw-1.9.1-0.txt        # you need to create a .txt license file

         echo "some terms of the restrictive package" > gdal-ecw-1.9.1-0.txt
         
       }}}

'''2. Steps for Testing extend Features of OSGeo4W :'''
[[BR]]
     * Before you follow this steps you should do all configurations and build the setup.exe at [http://trac.osgeo.org/osgeo4w/wiki/SetupDevelopment]
     * make the following:
       {{{ 
         Download "setup.override.ini"  file  from [http://trac.osgeo.org/osgeo4w/browser] in the root of your local directory 'C:\' 
         ./setup.exe  # run it.
        
         
       }}}
     * Choose the next option: Advance Install > Install from internet > Root Directory > Local package directory > Direct connection 
     * Choose a restrictive package for example 'gdal-mrsid' or 'gdal-ecw' or both,  you should to choose these because I just created a file for each 
       one in 'download.osgeo.org' server. If you choose another restrictive package setup.exe will raise an error, and choose another normal package for
       example: 'gdal-java'.
     * Setup will download the license file from remote server into your local directory "Local Package Directory" , you can see it if you want.
     * Next step setup.exe will load the file license into a window and it will show you.
