This version was developed under OS/2, initially with Perl 5.6, later
with Perl 5.8.2 and most recently with Perl 5.10.0, which is now
required.  The perl510.wpi build from Paul Smedley did not include
all of the CPAN packages that had been in my Perl 5.8.2, and I
downloaded the following from CPAN:

Digest-1.15.tar.gz
Digest-HMAC-1.01.tar.gz
Digest-SHA1-2.11.tar.gz
Email-ARF-0.006.tar.gz
Email::Date::Format
Email::MessageID
Email-MIME-1.910.tar.gz
Email-MIME-ContentType-1.015.tar.gz
Email::MIME::Encodings 1.313
Email-Simple-2.101.tar.gz

HTML-Tagset-3.20.tar.gz
IO-1.25.tar.gz
IO-stringy-2.110.tar.gz
MIME-tools-5.427.tar.gz
MIME::Types 1.13
MailTools-2.04.tar.gz
Net-DNS-0.67.tar.gz
Net-IP-1.25.tar.gz
Net-IP-Match-0.03.tar.gz
Net-IP-Match-Regexp-1.01.tar.gz
Params-Util-1.04.tar.gz
Regexp-Common-2.120.tar.gz
Test-Pod-1.26.tar.gz
Test-Simple-0.98.tar.gz
TimeDate-1.16.tar.gz
URI-1.37.tar.gz

I've added a module to Regexp::Common::URI,
Regexp::Common::URI::badhttp, but no longer use it; you don't need to
extract badhttp.pm into your Regexp\Comon\URI directory.

I currently don't use HTML::*.

To install, extract the three .conf files into the WHOIS subirectory
of %ETC%, copy the two .cmd files into a directory in your path and
configure the files. Normally the ETC directory will be \MPTN\ETC on
the boot drive for OS/2 and /etc for *ix and bsd.

Install all of the packages that I listed above. If you are using
CPANPLUS (CPANPLUS-0.9116), it will resolve dependencies for these:

    URI                            URI-1.59

For OS/2 you will need to update the extproc lines to reflect where
your Perl is located; for *ix and bsd you will need to remove the
extproc lines, update the shebang (#!) lines to reflect where your
Perl is located and mark the file executable with chmod.  I don't
know the windoze equivalent.  For *ix and bsd you will also need to
make the .cmd files executable with, e.g., chmod.

For all systems you will need to change the default value of $temp
or override it with the --temp <path> option.
