Which star do you mean, the first one or the second one?  I can't
really tell in my mail reader since Google Mail at some point dropped
the "show in fixed width font" option.

First one:

That's the splash operator which in this case unrolls an array
argument to multiple method arguments.

Second one:

Ruby's documentation is bad in places - but not that bad.  Try

ri19 'Dir.[]'
ri19 'Dir.glob'

Cheers
