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:
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.

Log message:
Fixed pkglint warnings. The warnings are mostly quoting issues, for
example MAKE_ENV+=FOO=${BAR} is changed to MAKE_ENV+=FOO=${BAR:Q}. Some
other changes are outlined in

    http://mail-index.netbsd.org/tech-pkg/2005/12/02/0034.html

Log message:
Add RMD160 digests.

Log message:
Fix installation if NO_MTREE is defined, as in the case for pkgviews.

Log message:
Fix bug where deinstallation wouldn't restore the original sendmail, etc.
as reported on tech-pkg@.  Bump the PKGREVISION.

Log message:
As suggested by reed@, use '.pkgsrc.mailwrapper' as the backup suffix so
that it's more apparent who owns that file.  Bump the PKGREVISION.

Log message:
Remove @exec/@unexec lines from PLIST and add INSTALL/DEINSTALL scripts
instead.  Be more careful about leaving a working MTA installation since
we're touching files in /usr.  Bump the PKGREVISION.

Log message:
Move WRKSRC definition away from the first paragraph in a Makefile.

Log message:
MESSAGE is NetBSD specific.
