# @summary Manages Apt configuration files.
#
# @see https://docs.puppetlabs.com/references/latest/type.html#file-attributes for more information on source and content parameters
#
# @param priority
#   Determines the order in which Apt processes the configuration file. Files with higher priority numbers are loaded first.
#
# @param ensure
#   Specifies whether the file should exist. Valid options: 'present', 'absent', and 'file'.
#
# @param source
#   Required, unless `content` is set. Specifies a source file to supply the content of the configuration file. Cannot be used in combination 
#   with `content`. Valid options: see link above for Puppet's native file type source attribute.
#
# @param content
#   Required, unless `source` is set. Directly supplies content for the configuration file. Cannot be used in combination with `source`. Valid 
#   options: see link above for Puppet's native file type content attribute.
#
# @param notify_update
#   Specifies whether to trigger an `apt-get update` run.
