91	Pseudo-portnames
92	----------------
93	Pseudo-portnames are words that may be used in place of a portname, and
94	which expand to some set of ports. The common pseudo-portnames are:
95	all, current, active, inactive, installed, uninstalled, and outdated.
96	These pseudo-portnames expand to the set of ports named.
97
98	Additional pseudo-portnames start with...
99	variants:, variant:, description:, portdir:, homepage:, epoch:,
100	platforms:, platform:, name:, long_description:, maintainers:,
101	maintainer:, categories:, category:, version:, and revision:.
102	These each select a set of ports based on a regex search of metadata
103	about the ports. In all such cases, a standard regex pattern following
104	the colon will be used to select the set of ports to which the
105	pseudo-portname expands.
106
107	Portnames that contain standard glob characters will be expanded to the
108	set of ports matching the glob pattern.
109
110	Port expressions
111	----------------
112	Portnames, port glob patterns, and pseudo-portnames may be logically
113	combined using expressions consisting of and, or, not, !, (, and ).
114
115	For more information
116	--------------------
117	See man pages: port(1), macports.conf(5), portfile(7), portgroup(7),
118	porthier(7), portstyle(7). Also, see http://www.macports.org.
