# Trivially, invoke as:

# make TARGET=riscos

# to cross-build for RO.

# Tested on unix platforms (building for GTK and cross-compiling for RO) and
|
|
# on RO (building for RO).

# To clean, invoke as above, with the 'clean' target

# To build developer Doxygen generated documentation, invoke as above,

# will see the following printed on screen:
|
|
# RISC OS
|
|
# In both cases HOST make variable is empty and we recover from that by
|
|
# assuming we're building on RISC OS.
|
|
# In case you don't see anything printed (including the warning), you
|
|
# have an update to date RISC OS build sytem. ;-)
