# There are 5 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)
#   debug -- command line Unix/Linux, for debugging
#   riscos_debug -- a cross between "riscos" and "debug"
#   gtk -- experimental gtk version
#
# "riscos", "riscos_small", and "riscos_debug" can be compiled under RISC OS,
# or cross-compiled using gccsdk.
