/*
   lldb.swig

   This is the input file for SWIG, to create the appropriate C++ wrappers and
   functions for various scripting languages, to enable them to call the
   liblldb Script Bridge functions.

%define DOCSTRING
"The lldb module contains the public APIs for Python binding.

Some of the important classes are described here:

* :py:class:`SBTarget`: Represents the target program running under the debugger.
* :py:class:`SBProcess`: Represents the process associated with the target program.
* :py:class:`SBThread`: Represents a thread of execution. :py:class:`SBProcess` contains SBThreads.
* :py:class:`SBFrame`: Represents one of the stack frames associated with a thread. :py:class:`SBThread`
  contains SBFrame(s).
* :py:class:`SBSymbolContext`: A container that stores various debugger related info.
* :py:class:`SBValue`: Represents the value of a variable, a register, or an expression.
* :py:class:`SBModule`: Represents an executable image and its associated object and symbol
  files.  :py:class:`SBTarget` contains SBModule.
* :py:class:`SBBreakpoint`: Represents a logical breakpoint and its associated settings.
  :py:class:`SBTarget` contains SBBreakpoints.
* :py:class:`SBSymbol`: Represents the symbol possibly associated with a stack frame.
* :py:class:`SBCompileUnit`: Represents a compilation unit, or compiled source file.
* :py:class:`SBFunction`: Represents a generic function, which can be inlined or not.
* :py:class:`SBBlock`: Represents a lexical block. :py:class:`SBFunction` contains SBBlocks.
* :py:class:`SBLineEntry`: Specifies an association with a contiguous range of instructions
  and a source file location. :py:class:`SBCompileUnit` contains SBLineEntry."

/*
Since version 3.0.9, swig's logic for importing the native module has changed in
a way that is incompatible with our usage of the python module as __init__.py
(See swig bug #769).  Fortunately, since version 3.0.11, swig provides a way for
us to override the module import logic to suit our needs. This does that.

Older swig versions will simply ignore this setting.
