This package provides a method for defining category code table stacks in LuaTeX. It builds on code provided by the 2015/10/01 release of LaTeX2e (also available as ltluatex.sty for plain users). It is required by the luatexbase package (v1.0 onward) which uses ctablestack to provide a back-compatibility form of this concept.

The TeX Live software distribution offers a complete TeX system for a variety of Unix, Macintosh, Windows and other platforms. It encompasses programs for editing, typesetting, previewing and printing of TeX documents in many different languages, and a large collection of TeX macros and font libraries. The distribution includes extensive general documentation about TeX, as well as the documentation for the included software packages.
Path searching library for TeX-related files
Kpathsea is a library and utility programs which provide path searching facilities for TeX file types, including the self- locating feature required for movable installations, layered on top of a general search mechanism.
Basic resource management for LuaTeX code
The bundle provides basic facilities for LuaTeX macro programmers, mostly resource allocation and convenience packages. Provided are: luatexbase-attr: attribute allocation; luatexbase-cctb: catcode table allocation; luatexbase-compat: compatibility helpers; luatexbase-loader: Lua module loading; luatexbase-modutils: Lua module declaration; luatexbase-mcb: callbacks extension; and luatexbase-regs: allocation of registers and the like. In addition, the (unadorned) luatexbase package loads all the above in one fell swoop.
Am I running under pdfTeX, XeTeX or LuaTeX?
The package, which works both for Plain TeX and for LaTeX, defines the \ifPDFTeX, \ifXeTeX, and \ifLuaTeX conditionals for testing which engine is being used for typesetting. The package also provides the \RequirePDFTeX, \RequireXeTeX, and \RequireLuaTeX commands which throw an error if pdfTeX, XeTeX or LuaTeX (respectively) is not the engine in use.
The package provides support for LaTeX documents to use many of the extensions offered by e-TeX; in particular, it modifies LaTeX's register allocation macros to make use of the extended register range. The etextools package provides macros that make more sophisticated use of e-TeX's facilities.
