Log message:
Remove USE_DIRS infrastructure support and support packages.

See http://mail-index.netbsd.org/pkgsrc-changes/2009/07/22/msg026834.html.

Log message:
Remove USE_DIRS from pkgsrc.

Shared directories can now be created independently by the pacakges
needing them and will be removed automatically by pkg_delete when empty.

Packages needing empty directories can use the @pkgdir command in PLIST.

Discussed and ok'd in thread starting at
http://mail-index.netbsd.org/tech-pkg/2009/06/30/msg003546.html

Log message:
Remove @dirrm related logic.

Log message:
Remove redundant NO_CHECKSUM and EXTRACT_ONLY definitions.

Log message:
Add DESTDIR support.

Log message:
Drop maintainership

Stop lying and drop maintainership of these packages.  I have not
maintained them for a very long time already, so leave room for
fresh blood to take over them.

Log message:
* If PLIST_SRC is explicitly set to an empty value in a package Makefile,
  then automatically generate a PLIST that says "${PKGNAME} has no files".

* If PLIST_SRC and GENERATE_PLIST are not set in a package Makefile,
  and no PLIST files exist, then fail during the package build with
  PKG_FAIL_REASON.

* Remove "intentionally empty" PLISTs again.

Now, the easy way to say that a package installs no files is to just
add the following to the package Makefile:

	PLIST_SRC=	# empty

Log message:
Re-add "intentionally empty" PLISTs for meta-packages and other packages
that directly manipulate empty PLISTs.

Modify plist/plist.mk so that if the PLIST files are missing and no
GENERATE_PLIST is defined, then the package fails to build.

Log message:
Remove empty PLISTs from pkgsrc since revision 1.33 of plist/plist.mk
can handle packages having no PLIST files.

Log message:
Remove USE_PKGINSTALL from pkgsrc now that mk/install/pkginstall.mk
automatically detects whether we want the pkginstall machinery to be
used by the package Makefile.
