The Puppet Core uses a `.yardopts` file that hides all docstrings that do not
have an API tag. This patch is a hack that allows `puppet yardoc` to extract
documentation for parser functions shipped in the core.
FIXME: This isn't the right way to solve the problem. The right way to solve
the problem is to adjust the Puppet `.yardopts` file to a sane value.
This handler triggers on all occurrences of `newfunction` and parses the
parameters passed to that method in order to generate documentation. The
implementation is a good experiment in extracting documentation without
evaluating Ruby code. However, the generality of this approach may ultimately
be doomed by the use of metaprogramming in custom Types and Providers.
