Synopsis provides multiple representations of the parsed code, on different
levels of granularity. Some of them are exposed using Python, some using C++.

Synopsis contains two basic parts: A C++ library, providing an API to
parse and analyze C and C++ source files, as well as a Python package
to parse and analyze IDL, C, C++, and Python code. While the former
provides fine-grained access to the low-level representations such as
<span class="emphasis"><em>Parse Tree</em></span> and <span class="emphasis"><em>Symbol Table</em></span>,
the latter operates on an <span class="emphasis"><em>Abstract Semantic Graph</em></span>.
</p><p>
Most of the <span class="type">Processor</span>classes from the Python API are written
in pure Python, but some (notably the parser classes) are actual extension
modules that use the low-level APIs from the C++ API.

Following the hybrid nature of the project, the source layout has
two more or less separate root directories. <code class="filename">Synopsis/</code>
provides the <span class="type">Synopsis</span> Python package, while
<code class="filename">src/</code> contains the sources for the C++ API.
