Log message:
Bump BUILDLINK_ABI_DEPENDS.png and PKGREVISION for png-1.2.9nb2 update.

Log message:
Point MAINTAINER to pkgsrc-users@NetBSD.org in the case where no
developer is officially maintaining the package.

The rationale for changing this from "tech-pkg" to \ 
"pkgsrc-users" is
that it implies that any user can try to maintain the package (by
submitting patches to the mailing list).  Since the folks most likely
to care about the package are the folks that want to use it or are
already using it, this would leverage the energy of users who aren't
developers.

Log message:
Recursive revision bump / recommended bump for gettext ABI change.

Log message:
Bump BUILDLINK_RECOMMENDED of textproc/expat to 2.0.0 because
of the shlib major bump.
PKGREVISION++ for the dependencies.

Log message:
Add missing article in comment.

Log message:
Remove the abuse of buildlink that was pkg-config/buildlink3.mk.  That
file's sole purpose was to provide a dependency on pkg-config and set
some environment variables.  Instead, turn pkg-config into a "tool"
in the tools framework, where the pkg-config wrapper automatically
adds PKG_CONFIG_LIBDIR to the environment before invoking the real
pkg-config.

For all package Makefiles that included pkg-config/buildlink3.mk, remove
that inclusion and replace it with USE_TOOLS+=pkg-config.

Log message:
Reset MAINTAINER -- he stopped working on pkgsrc.

Log message:
Change path from devel/pkgconfig to devel/pkg-config.
No PKGREVISION bump since pkg-config is only a BUILD_DEPENDS.

Log message:
Remove USE_GNU_TOOLS and replace with the correct USE_TOOLS definitions:

	USE_GNU_TOOLS	-> USE_TOOLS
	awk		-> gawk
	m4		-> gm4
	make		-> gmake
	sed		-> gsed
	yacc		-> bison

Log message:
Remove USE_BUILDLINK3 and NO_BUILDLINK; these are no longer used.
