Lua.xclangspec

// Lua
//  Lua.xclangspec v3.0.1

//  Lua language specification for Xcode 1.5. */
//  Bret Victor, 4/24/2005

//  Based on SubEthaEdit's Lua mode, and the built-in Xcode language specs at:
//  /System/Library/PrivateFrameworks/DevToolsCore.framework/Versions/A/Resources/Built-in languages.pblangspec

//  Up dated to Lua 5.1 syntax by Graham Henstridge, 24/10/2006 and confirmed
//  operational with Xcode 2.4.

//  Updated 1/12/07 to Xcode3 by Graham Henstridge, with a  little help from
//  David Ewing at Apple
//  Uses the new .xclangspec format, the definition of which is not available,
//  however using various files at:
//  /Developer/Library/PrivateFrameworks/XcodeEdit.framework/Versions/A/Resources/
//  assists in understanding the language.

//  Place this file Lua.xclangspec and Lua.pbfilespec in directory:
//  ~/Library/Application Support/Developer/Shared/Xcode/Specifications/
