evaluate a library to parse program options

[ChristianBeer]

Find a library that helps with parsing program options. Examples would be GNU getopt or Boost.Program_options or something similar.

Requirements:

• must support short options with (-o value) and without (-v) arguments
• must support long options with (--option value) and without (--help) arguments
• long options do not need to have short options (but it could be possible in the future)
• must support detached sources like the trickle_handler framework: see trickle_handler.cpp and trickle_deadline.cpp
