  +== Applying and using the patch to install VirtualBox from the package file
   
   If you like package installations to be marked clean and report no errors,
   you should patch the downloaded package to include the enhanced script.
  
positive.code: sources for hints on configuration, and copy and tune the needed config
  files as `/etc/X11/xorg.conf*` names referenced in the script variables
  (as is, or renamed via its own optional simple config file).
  
  Good luck,

  = Applying and using the patch to (un)install a VirtualBox package
  
  There are two approaches: partially install the unmodified package, fail
  in the configuration step on an unsupported OS, patch the installed script
  and resume configuration to complete the installation, or to fix the SVR4
  package file. The former is more simple in practice, while the latter is
  more suitable for distro maintainers or LAN admins who want to suffer the
  complicated procedure once per upgrade, not once per host.

  NOTE: Thanks to "russell" from the OpenIndiana mailing list for pointing
  in the right direction for this simplified procedure.
