Everything is now configured.  To compile libopm now, just type make.  It
requires GNU Make, which may be installed as gmake on your system.

libopm will be installed in /home/camell/bopm.  To change this, run:
   ./configure --prefix=DIRECTORY

Everything is now configured, but you can find some more (infrequently
changed) options in options.h.  To compile BOPM now, just type make.  It
requires GNU Make, which may be installed as gmake on your system.

bopm will be installed in ${HOME}/bopm.  To change this, run:
   ./configure --prefix=DIRECTORY

If possible, PLEASE CONTRIBUTE TO OUR DNSBL BY REPORTING YOUR PROXIES!!

o What is DNSBL?
    It's the database of open proxies we provide and your BOPM checks
    against BEFORE bothering to scan the client, therefore killing KNOWN
    proxies faster and more efficiently.

o Why should my network contribute?
    Because the more that do, the more proxies we know about and the
    better the service becomes for all BOPM users including YOU!  People
    are also using our DNSBL to block spam (spammers use open proxies
    too!) so you'd be helping the whole Internet.

o Sounds complicated, what do you need?
    BOPM is already designed to report the proxies you find, but it is
    turned off by default.  To enable it all you have to do is:
      - Set DNSBL_FROM to a unique email address that we can contact you
        at if there is ever any problem with your reports.
      - Email us now at [email protected] to tell us what you have
        set your DNSBL_FROM to.
      - Set DNSBL_TO to [email protected].
      - Set SENDMAIL to contain the path to your sendmail binary (even
        if you don't use sendmail you will have a binary named sendmail in
        /usr/sbin or /usr/lib.

For more info about the people who already report their proxies, please
see http://www.blitzed.org/bopm/   - Thank you!
