ACK, thanks. :-)

Yeah, I knew, I was thinking 'emulated' enum, as class-level constants, like:

    class Package():
        T_UNKNOWN_PKG = 0
        T_HOST_PKG = 1
        T_TARGET_PK = 2
        [...]

and then refer to them as Package.T_HOST_PKG etc...

(but of course, they are not constant! they are just class-variables
with default values.)

Eh! ;-)
