22/// PDBContext
23/// This data structure is the top level entity that deals with PDB debug
24/// information parsing.  This data structure exists only when there is a
25/// need for a transparent interface to different debug information formats
26/// (e.g. PDB and DWARF).  More control and power over the debug information
27/// access can be had by using the PDB interfaces directly.
