bjam glob 'exclude pattern' question

According to the docs, bjam's glob operator accepts a 2nd argument which specifies a pattern to exclude, like so:

[ glob pattern : excl开发者_如何学Goude ]

However bjam gives me an error complaining about the 2nd argument. It may be that my bjam version is too old. Would anyone know at what version this 'exclude' feature was added? I'm using 3.1.17.

We're using 3.1.16 of Boost.Jam and Milestone 12 of Boost.Build, and the exclude parameter works fine for us. What's your exact pattern and exclude arguments?
