define Package/3proxy/description
  3Proxy tiny free proxy server is really tiny cross-platform (Win32/Win64&Unix)
  freeware proxy servers set. It includes HTTP proxy with HTTPS and FTP support,
  SOCKSv4/SOCKSv4.5/SOCKSv5 proxy (socks/socks.exe), POP3 proxy, SMTP proxy,
  AIM/ICQ proxy (icqpr/icqpr.exe), MSN messenger / Live messenger proxy
  (msnpr/msnpr.exe), FTP proxy, caching DNS proxy, TCP and UDP portmappers.

  You can use every proxy as a standalone program (socks, proxy, tcppm, udppm,
  pop3p) or use combined program (3proxy). Combined proxy additionally supports
  features like access control, bandwidth limiting, limiting daily/weekly/monthly
  traffic amount, proxy chaining, log rotation, syslog and ODBC logging, etc.

  It's created to be small, simple and yet very functional.
