- They now have an SBCommandReturnObject instead of an SBStream as third argument - The class CommandObjectPythonFunction has been merged into CommandObjectCommands.cpp - The command to manage them is now: command script with subcommands add, list, delete, clear command alias is returned to its previous functionality - Python commands are now part of an user dictionary, instead of being seen as aliases llvm-svn: 137785
