 # $FreeBSD$
 #
 # Provide support for ports requiring Emacs.  This includes flavors with proper
 # dependencies and useful variables.
 #
-# Feature:		emacs
-# Usage:		USES=emacs or USES=emacs:args
+# Feature:	emacs
+# Usage:	USES=emacs or USES=emacs:args
 # Valid ARGS:	build, run
 #
-# build			Indicates that Emacs is needed at build time.
-# run			Indicates that Emacs is needed at run time.
+# build		Indicates that Emacs is needed at build time.
+# run		Indicates that Emacs is needed at run time.
 #
 # If build and run are omitted from the argument list, Emacs will be added to
 # BUILD_DEPENDS and RUN_DEPENDS.  EMACS_NO_DEPENDS can be set to prevent both
 # Emacs dependencies.
 #
 # Variables, which can be set in make.conf:
-# DEFAULT_VERSIONS+=          The default flavor for Emacs ports can be added to
-#                             DEFAULT_VERSIONS.  For example,
+# DEFAULT_VERSIONS+=          The default flavor for Emacs ports (ports with
+#                             USES=emacs, but not the Emacs ports themselves)
+#                             can be added to DEFAULT_VERSIONS.  For example,
 #                             DEFAULT_VERSIONS+= emacs=nox
 #                             Valid flavors: full canna nox devel_full devel_nox
 #                             Flavors specified on the command line take precedence.
 #
 # Variables, which can be set by ports:
 # EMACS_FLAVORS_EXCLUDE:      Do NOT build these Emacs flavors.
 #                             If EMACS_FLAVORS_EXCLUDE is not define then all
 #                             valid Emacs flavors are assumed.
 #
 # EMACS_NO_DEPENDS:           Do NOT add build or run dependencies on Emacs.
 #
 # Variables, which can be read by ports:
 # EMACS_CMD:                  Emacs command with full path (e.g. /usr/local/bin/emacs-25.3)
 # EMACS_FLAVOR:               Used for dependencies (e.g. BUILD_DEPENDS= dash.el${EMACS_PKGNAMESUFFIX}>0:devel/dash@${EMACS_FLAVOR})
 # EMACS_LIBDIR:               Emacs Library directory without ${PREFIX} (e.g. share/emacs)
 # EMACS_LIBDIR_WITH_VER:      Library directory without ${PREFIX} including version (e.g. share/emacs/25.3)
 # EMACS_MAJOR_VER:            Emacs major version (e.g. 25)
 # EMACS_PKGNAMESUFFIX:        PKGNAMESUFFIX to distinguish Emacs flavors
 # EMACS_SITE_LISPDIR:         Emacs site-lisp directory without ${PREFIX} (e.g. share/emacs/site-lisp)
 # EMACS_VER:                  Emacs version (e.g. 25.3)
 # EMACS_VERSION_SITE_LISPDIR: Include version (e.g. share/emacs/25.3/site-lisp)
