[Boost-users] [program_options] Configuration file syntax (or how to fill a vector from the configuration file)

Hi, is there a general description of the config file syntax that program_options uses available? Like if it's case-sensitive, if you can quote arguments, etc ... currently i'm wondering if I can fill a vector from one line, like val = foo bar baz with foo, bar, and baz as the values ... is this possible with some separator?
