# output will occur in bin.x.proc
# where x is debug or opt and proc is ix86 or amd64
# You must use this script from the amxmodx src dir

#options = 
# jit - use the JIT
# debug - enable gdb debugging
# amd64 - compile for AMD64 (impiles no jit)
# proc=ix86 - assumed not amd64
# clean - clean the specifications above
# asm - for ASM implementation
# !! TODO - add memory mananger support
# lineop - for JIT only, uses slow version
