Description:

The bundle holds prototype implementations of concepts for a
LaTeX designer interface, to be used with the experimental
LaTeX kernel as programming tools and kernel support. Packages
provided in this release are: - l3keys2e, which makes the
facilities of the kernel module l3keys available for use by
LaTeX 2e packages; - xfrac, which provides flexible split-level
fractions; - xparse, which provides a high-level interface for
declaring document commands; and - xtemplate, which provides a
means of defining generic functions using a key-value syntax.
All the files of the bundle are also available in the
Subversion (SVN) repository of the LaTeX3 Project. The bundle
on CTAN is based on a snapshot of the SVN repository on 2012-
09-30.
