Good, thanks!

Hmmm... not really? Certainly not in the "dependencies" section :-)

Thanks for the explanation: this clarifies things a bit. However, the
"CMake" example was just copy+paste'd from the docs. What I need is to
insert a dependency on the Boost library.
So let me ask more specific questions: Assume I want to specify a
dependency on `Boost-1.58.0-foss-2015b-Python-2.7.10.eb` Would that
translate into the following dependency tuple?
('Boost', '1.58.0', 'Python-2.7.10', ('foss', '2015b'))
Would the following tuple also match that `.eb` file?
('Boost', '1.58.0')
Thanks,
Riccardo
