# Usage: rtfl-filter-out-classes [<classes> ...]
#
# Filter out all RTFL messages referring to objects belonging to a
# specified set of classes. Each command line argument is a concrete
# class or a (filename) pattern. The latter is useful to exclude whole
# namespaces ("path::to::namespace::*").
#
# N. b. that parsing is slightly incorrect; escaping is (except partly
# for classes) not considered.
