Usage: cons [-h] [ -- [release|debug] [novm] [noso] [nosmp] [master_server=<adr>] [auth_server=<adr>] [auth_port=<port>] [pk3] [bspc] [setup] [sdk]]
Default build type is Debug, specifying '-- release' on the
command line builds a Release version (NOTE that this option
only affects the native libraries).

novm: will not build the VMs
noso: will not build the so

below are for core builds only:

nosmp : do not build the SMP-enabled version of the renderer
pk3   : generate the pk3s on the fly (defined in unix/Conscript-pk3)
bspc  : build bspc
setup : build setup 
sdk   : build the mod sdk
