# The license of vpnc (Gpl >= 2) is quite likely incompatible with the
# openssl license. Openssl is one possible library used to provide certificate
# support for vpnc (hybrid only).
# While it is OK for users to build their own binaries linking in openssl
# with vpnc and even providing dynamically linked binaries it is probably
# not OK to provide the binaries inside a distribution.
# See http://www.gnome.org/~markmc/openssl-and-the-gpl.html for further
# details.
# Some distributions like Suse and Fedora seem to think otherwise.
# Comment this in to obtain a binary with certificate support which is
# GPL incompliant though.
