I know, but it's a start.

The real work is actually done by Boost.Filesystem and Boost.Regex. All I
do is transform the glob into an equivalent regex using Boost.Spirit and
then loop recursively over the "pattern tree" to build up the list of
matching files. I think I've got all the corner cases covered, but the
test suite will evolve...

PS, here's the test at the moment. "succeeded" means that the expected
number of matches were found.

$ ls -a
../../../bin/boost/libs/glob/test/test_glob.test/gcc/debug/glob_test_dir/
.        fooabar  foo-bar  foo?bar  foo{bar  foobbar  foo.cxx
..       foo^bar  foo,bar  foo[bar  foo}bar  foocbar  foo.hpp
foo1bar  foo bar  foo!bar  foo]bar  foo*bar  foo.cpp  .oobar
