+Wildcard OS_NAME
+----------------
+
+Some package managers are supported and function on more than one platform, and
+the names of packages in those package managers are typically the same between
+platforms.  To avoid duplicating the rules under several ``OS_NAME`` stanzas the
+``OS_NAME`` can be specified as `*` as long as the rule under it specifies the
+``PACKAGE_MANAGER`` explicitly.
+
+Similar to rule lookups regarding a `Wildcard OS_VERSION`_, an explicit
+``OS_NAME`` entry will take precedence over `*` rules entirely and an
+explicitly null ``PACKAGE_ARGUMENT`` for an ``OS_NAME`` will omit it from the
+wildcard.
