#   7zip package provider.  This parameter only applies to Windows where it defaults to `chocolatey`. Can be set to an empty string, (or `undef` via hiera), if you don't want this module to manage 7zip.
# @param seven_zip_source
#   Alternative package source for 7zip.  This parameter only applies to Windows.
