  Fixing registerClass. No more wrap: unnecessary attributes
  Fixed registerMethod to work like registerVariable
  Switched to Swig_name_* functions
  Return MIN_OPT_LEVEL for elua
  add nspace_extend test case
  updated documentation following comd options renaming
  Options in alphabetical order
  Members renaming
  target_name -> lua_name
  Fixing cmd options, again
  Fixing segfault
  Removed class_parent_nspace
  Fixes to module options
  Rename methods to make it clear what 'symbols table' they operate on.
  Small documenation fixes
  Updating Lua documentation
  Eliminating namespaces_hash and using symbols table instead
  Attempt to catch unreproducable bug from Travis CI build
  Small bugfixes
  Bugfixes for eLua. eLua emulation mode
  Add compatibility option for old-style inheritance
  Add support for C-style enums in C mode. And tests.
  Style fixes. Comments fixes. Fixing cmd options. etc
  Some fixes for elua
  Attempt to fix unreproducable bug (from Travis CI build)
  Fixes for examples. Wrapped keywords into guardian in keyword_rename test
  Remove some typos
  Remove some obsolete code
  Manually beautifying luarun.swg
  Code beautifier
  Valuewrapper test
  Removing obsolete debug code
  Bugfixes
