# build a patched version of GnuTLS version 2.4.x, including the
# ability to parse and accept the GNU S2K extension known as
# "gnu-dummy" (which doesn't have any secret key data at all)

# Note: you probably want to prepare your build system in the
# following way:

# apt-get build-dep libgnutls26
# aptitude install devscripts fakeroot
