[antlr-interest] Ignoring tokens in AnTLR+Python

Hello everyone!
I am fairly new to AnTLR. I am working on an interpreter for
configuration files ('configure.ac' files i should say); but I don't
need to scan every single token on the files, only variable assignments
and one or another macro so, my question is:
How can I ignore every other sentence on the files?
At first I intended to do something like
SENTENCE: ASSIGNMENT | MACRO | OTHER;
OTHER: ~(ASSIGNMENT | MACRO)
but i get that ~TOKEN is not allowed in lexer. Is there a way to achieve
this without me having to define the entire grammar of 'configure.ac' files?
Best regards,
D.H. Bahr
PS: As remarked in subject I am using python and not Java or C.
