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

Log message:
NROFF isn't used here; don't define it.

Log message:
Don't build catpages inside the package.  Not every system has a nroff
shipped standard.

Log message:
Don't "cp -p" for *source* files.  Builds are usually done as an \ 
unprivileged
user, so it's not nice to try to use an option that will try to chown if
the repository isn't owned by the builder.

(Some OS's do in fact cause an error when the chown in "cp -p" fails.)

Log message:
Change pkgclean to wait for the termination of all the child processes.
This fix comes from Peter Postma, and it addresses a problem reported
by Ryo HAYASAKA in PR#27250.

Log message:
* Make PKGSRC_TOPDIR a private variable by renaming it to _PKGSRC_TOPDIR,
  as it's only used internally by bsd.prefs.mk.

* Make _PKGSRCDIR a public variable by renaming it to PKGSRCDIR.
  Also, generate its value from ${_PKGSRC_TOPDIR} so it's less fragile
  than the old method of stripping off the last two components of
  ${.CURDIR}.  PKGSRCDIR may now be used after bsd.prefs.mk is defined.

* Change all references to _PKGSRCDIR to PKGSRCDIR.

Log message:
Initial import of pkgclean-20040622 from pkgsrc-wip, written by
Peter Postma.

pkgclean cleans up your pkgsrc by removing the work directories.
It's a fast alternative for ``cd /usr/pkgsrc && make clean''.
