+  <longdescription>
+    macrostep is an Emacs minor mode for interactively stepping through the
+    expansion of macros in Emacs Lisp source code. It lets you see exactly what
+    happens at each step of the expansion process by pretty-printing the
+    expanded forms inline in the source buffer, which is temporarily read-only
+    while macro expansions are visible. You can expand and collapse macro forms
+    one step at a time, and evaluate or instrument the expansions for debugging
+    with Edebug as normal. Single-stepping through the expansion is
+    particularly useful for debugging macros that expand into another macro
+    form. These can be difficult to debug with Emacs’ built-in macroexpand,
+    which continues expansion until the top-level form is no longer a macro
+    call.
