/*
   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.

"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.

The different enums in the `lldb` module are described in :doc:`python_api_enums`.

/*
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.
