# these are the check currently impleted.
#  
# first argument is the name of the check, printed by the warning.
#   ex : xmms.
#
# secund argument is the regular expression of the naming policy.
#   ex: xmms plugin should be named xmms-name_of_plugin.
#
# third is the path of the file that should contains a package to be related to the naming scheme.
#   ex: xmms plugin are put under /usr/lib/xmms/
#
# the module is far from being perfect since you need to check this file for the naming file.
# if somone as a elegant solution, I will be happy to implement and test it.
