# There are 6 possible builds of NetSurf:
#
#   riscos -- standard RISC OS build
#   riscos_small -- identical to "riscos", but linked with smaller libraries
#   		(no openssl, and libcurl without ssl support)
#   ncos -- NCOS build (variant of RISC OS for Network Computers)
#   debug -- command line Unix/Linux, for debugging
#   riscos_debug -- a cross between "riscos" and "debug"
#   gtk -- experimental gtk version
#
# "riscos", "riscos_small", "ncos", and "riscos_debug" can be compiled under
# RISC OS, or cross-compiled using GCCSDK.
