7) Subversion installation
  - The LibreSource Subversion service manage dynamicaly the 
    subversion configuration files for user authentication and 
    security management. Thus, in order to use this services, 
    a subversion server must be installed and configured to used 
    those generated files.
  - Configure LibreSource for your subversion (Properties to defined in $LIBRESOURCE_HOME/Distribution/ls-config.properties)
      > subversion.authz.file.path      : Specify the path to the authz file that your Subversion should use (security mapping)
      > subversion.passwd.file.path     : Specify the path to the passwd file that your Subversion should use (user authentication)
      > subversion.repository.base.path : Working area for LibreSource. Should be set by the administrateur as the root 
      > subversion.admin.login          : Subversion Libresource superuser
      > subversion.admin.password       : Subversion Libresource superuser password
  - Configure the Subversion installation
      > Create only one repository that should respond at svn://YOUR_LS_SERVER/ls-svn
      > Check-out the content of this repository
         + svn co svn://forge.artenum.com/ls-svn  "THE_PATH_YOU_SET_FOR_LS_subversion.repository.base.path"
      > Delete all the repository content and commit
         + cd "THE_PATH_YOU_SET_FOR_LS_subversion.repository.base.path"
         + svn delete trunk
         + svn delete tags
         + svn delete branches
         + svn commit -m "Initialisation"
      > Edit the configuration file "svnserve.conf" (authz/passwd should refer to the file path specified in LibreSource)
