# == Class: postfix::virtual_regexp
#
# Manages Postfix virtual_regexp by merging snippets shipped:
# - in the module's files/virtual_regexp.d/ or puppet:///files/etc/postfix/virtual_regexp.d
#   (the latter takes precedence if present); site_postfix module is supported
#   as well, see the source argument of file {"$postfix_virtual_regexp_snippets_dir"
#   bellow for details.
# - via postfix::virtual_regexp_snippet defines
#
# Example usage:
# 
#   node "toto.example.com" {
#     class { 'postfix':
#       manage_virtual_regexp => 'yes',
#     }
#     postfix::config { "virtual_alias_maps":
#       value => 'hash://postfix/virtual, regexp:/etc/postfix/virtual_regexp',
#     }
#   }
