+    (description
+     "The package provides the means of writing code in a modular fashion: big
+macros or functions are divided into small chunks (called gates) with names,
+which can be externally controlled (e.g., they can be disabled, subjected to
+conditionals, loops...) and/or augmented with new chunks.  Thus complex code
+may easily be customised without having to rewrite it, or even understand its
+implementation: the behavior of existing gates can be modified, and new ones
+can be added, without endangering the whole design.  This allows code to be
+hacked in ways the original authors might have never envisioned.  The
+@code{gates} package is implemented independently for both TeX and Lua.  The
+TeX implementation, running in any current environment, requires the
+@code{texapi} package, whereas the Lua version can be run with any Lua
+interpreter, not just LuaTeX.")
