#-     can be a regexp, array ref or Perl code (parameters: driver)
#- o description:
#-     full name of the device
#- o name: name used by the packages

#- the following fields are optional:
#- o url:
#-     url where the user can find tools/drivers/firmwares for this device
#- o device:
#-     device in /dev to be configured
#- o post:
#-     command to be run after all packages are installed
#-     can be a shell command or Perl code
#- o restart_service:
#-     if exists but not 1, name of the service to be restarted
#-     if 1, specify that the service named by the name field should be restarted
#- o tools:
#-     hash of the tools settings
#-     test_file field required
#-     if package field doesn't exist, 'name' is used
#- o kernel_module:
#-     if exists but not 1, hash of the module settings
#-     if 1, kernel modules are needed and use the name field
#-         (name-kernel or dkms-name)
#- o firmware:
#-     hash of the firmware settings
#-     test_file field required
#-     if package field doesn't exist, 'name-firmware' is used

#- hash of package settings structure:
#- o package:
#-     name of the package to be installed for these device
#- o test_file:
#-     file used to test if the package is installed
#- o prefix:
#-     path of the files that are tested
#- o links:
#-     useful links for this device
#-     can be a single link or array ref
#- o user_install:
#-     function to call if the package installation fails
#- o explanations:
#-     additionnal text to display if the installation fails
#- o no_club:
#-     1 if the package isn't available on Mandriva club
