F-Engrave tries to use “psyco” for speedup. Don’t know if psyco is available for mac. It is also unmaintained. Maybe the script could be improved with pypy for all platforms. Any python pros out there?
try:
import psyco
psyco.full()
sys.stdout.write("(Psyco loaded: You have the fastest F-Engrave.)\n")
except:
pass
