-# look at the example below - the output dir is lib/gssapi, the source asn1 file is lib/gssapi/spnego/spnego.asn1
-# well ... hmm, it depens if any heimdal C file uses a #include that depends on the path. We can try a different location
-# but I'm guessing it will break the heimdal C files
-# too hard to use a different output dir from input?
-# the restriction is we can't modify the existing C source of heimdal.
-# ok, symlink hacks to solve? it should be similar to the gen_ndr hackery of PIDL
-# as that is also a different out dir from input file
-# ok, but is it OK for PIDL? pidl is putting output in ../gen_ndr/ndr_$NAME.[ch] etc
