Changes since 1.4:
* Converted to automake/autoconf for configuration, which should make
it easier to extend portability.
* Added support for checking multiple addresses in one invokation.
* Added support for reading addresses to check from standard input, by
specifying an argument of '-'.
* Changed rbl.dorkslayers.com to relays.orbs.org, due to a change in
management.
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.
