FOOTNOTES
=========

  *1 = requires a TLS library
  *2 = requires OpenLDAP or WinLDAP
  *3 = requires a GSS-API implementation (such as Heimdal or MIT Kerberos) or
       SSPI (native Windows)
  *4 = requires a GSS-API implementation, however, only Windows SSPI is
       currently supported
  *5 = requires nghttp2 and possibly a recent TLS library
  *6 = requires c-ares
  *7 = requires OpenSSL, NSS, GSKit, WinSSL or Secure Transport; GnuTLS, for
       example, only supports SSLv3 and TLSv1
  *8 = requires libssh2
  *9 = requires OpenSSL, GnuTLS, mbedTLS, NSS, yassl, Secure Transport or SSPI
       (native Windows)
  *10 = requires an SSL library that supports SSLv3
  *11 = requires libidn or Windows
  *12 = requires libz
  *13 = requires libmetalink, and either an Apple or Microsoft operating
        system, or OpenSSL, or GnuTLS, or NSS
  *14 = requires a GSS-API implementation (such as Heimdal or MIT Kerberos)
