cannot get autoload to work

Hi,

I'm trying to get autoloading to work with gdb 7.6.1. From the
documentation I gather there are two ways to plug in autoloading
scripts:
 - using objfile-gdb.py files
 - or using the DEFINE_GDB_SCRIPT macro

I can't seem to get any of them working. I have a bunch of
spidermonkey pretty printers that seem to be built with autoloading in
mind. Since there weren't any objfile-gdb.py style printers I tried
with the macro.
The docu says "gdb will look for each specified script file first in
the current directory".

Which is the current dir in this case? - the dir where I start gdb, or
the one with the executable or what?

Can you point me to examples of both approaches so that I can be able
to auto-load pretty printers for my own types?

Thanks,
Bobby
