+# The pthreads strategy for pkgsrc is to "bless" a particular pthread
+# package as the Official Pthread Replacement (OPR).  A package that uses
+# pthreads may do one of the following:
+#
+#   (1) Simply include pthread.buildlink3.mk.  This will make the package
+#	use the native pthread library if it's available, or else the OPR
+#	package.  The value of PTHREAD_TYPE may be checked to be either
+#	"native", or the name of the OPR package, or "none", e.g.
+#
+#	#
+#	# package Makefile stuff...
+#	#
+#	.include "../../mk/pthread.buildlink3.mk"
+#
+#	.if defined(PTHREAD_TYPE) && ${PTHREAD_TYPE} == "none"

+#	.endif
+#
+#	.include "../../mk/bsd.pkg.mk"
+#
+#	Note that it's only safe to check and use the value of PTHREAD_TYPE
+#	after all other buildlink3.mk files have been included.
+#
+#   (2) Add "native" to PTHREAD_OPTS prior to including
+#	pthread.buildlink3.mk.  This is like case (1), but we only check for
+#	the native pthread library, e.g.,
+#
+#	PTHREAD_OPTS+=	native
+#	#
+#	# package Makefile stuff...
+#	#
+#	.include "../../mk/pthread.buildlink3.mk"

+#
+#	.include "../../mk/bsd.pkg.mk"
+#
+#   (3)	Add "require" to PTHREAD_OPTS prior to including
+#	pthread.buildlink3.mk.  This will make the package use the native
+#	pthread library or else use the OPR package, and will otherwise set
+#	PKG_SKIP_REASON if neither can be used, e.g.,
+#
+#	PTHREAD_OPTS+=	require
+#	#
+#	# package Makefile stuff...
+#	#
+#	.include "../../mk/pthread.buildlink3.mk"
+#	.include "../../mk/bsd.pkg.mk"
+#
+#   (4) Add both "require" and "native" to PTHREAD_OPTS prior to including
+#	pthread.buildlink3.mk.  This is like case (3), but we only check for
+#	the native pthread library, e.g.,
+#
+#	PTHREAD_OPTS+=	require native
+#	#
+#	# more package Makefile stuff...
+#	#
+#	.include "../../mk/pthread.buildlink3.mk"
+#	.include "../../mk/bsd.pkg.mk"
+#
+# The case where a package must use either the native pthread library or
+# some pthread package aside from the OPR is a special case of (2), e.g.,
+# if the required pthread package is "ptl2", then:
+#
+#	PTHREAD_OPTS+=	native
