Dwgrep is a tool, an associated language (called Zwerg) and a library
(libzwerg) for querying Dwarf (debuginfo) graphs.

You can think of dwgrep expressions as instructions describing a path
through a graph, with assertions about the type of nodes along the way:
that a node is of given type, that it has a given attribute, etc. There
are also means of expressing sub-conditions, i.e. assertions that a given
node is acceptable if a separate expression matches (or does not match)
a different path through the graph.
