LaTeX3 High-Level Concepts ========================== Overview -------- The `l3packages` collection is contains implementations for aspects of the LaTeX3 kernel, dealing with higher-level ideas such as the Designer Interface. The packages here are considered broadly stable (The LaTeX3 Project does not expect the interfaces to alter radically). These packages are build on LaTeX2e conventions at the interface level, and so may not migrate in the current form to a stand-alone LaTeX3 format. All of the material in the collection requires the LaTeX3 base layer package [`l3kernel`](http://ctan.org/pkg/l3kernel). The two packages must be installed in matching versions: if you update l3packages, make sure that `l3kernel` is updated at the same time. Currently included in the CTAN release of `l3packages` are the following bundles: * `l3keys2e` * `xfrac` * `xparse` * `xtemplate` `l3keys2e` ---------- The `l3keys2e` package allows keys defined using `l3keys` to be used as package and class options with LaTeX2e. This is tied to the method the existing kernel uses for processing options, and so it is likely that a stand-alone LaTeX3 kernel will use a very different approach. `xfrac` ------- The `xfrac` package uses the interface defined by `xtemplate` to provide flexible split-level fractions _via_ the `\sfrac` macro. This is both a demonstration of the power of the template concept and also a useful addition to the available functionality in LaTeX2e. `xparse` ------- The `xparse` package provides a high-level interface for declaring document commands, e.g., a uniform way to define commands taking optional arguments, optional stars (and others), mandatory arguments and more. `xtemplate` ----------- The `xtemplate` package provides an interface for defining generic functions using a key=val syntax. This is designed to be "self-documenting", with the key definitions providing information on how they are to be used. Discussion ---------- Discussion concerning the approach, suggestions for improvements, changes, additions, _etc._ should be addressed to the list [LaTeX-L](http://news.gmane.org/group/gmane.comp.tex.latex.latex3).

More general discussion should be directed to the LaTeX-L lists. The LaTeX3 Project ------------------ Development of LaTeX3 is carried out by [The LaTeX3 Project](http://www.latex-project.org/latex3.html).

xtemplate – A high-level interface for declaring document commands
The package provides a mechanism for defining templates,
which are parameterised definitions of aspects of document
design. Templates are the tool through which document designers
can select the features of their document.
The package on CTAN derives from a snapshot of the LaTeX 3 repository, taken on 2012-07-16, and is distributed as part of the l3packages bundle.
