l3­pack­ages – High-level LaTeX3 con­cepts

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 2012-11-21.
