+synopsis: "Standard infrastructure for ppx rewriters"
+description: """
+Ppxlib is the standard infrastructure for ppx rewriters
+and other programs that manipulate the in-memory representation of
+OCaml programs, a.k.a the "Parsetree".
+
+It also comes bundled with two ppx rewriters that are commonly used to
+write tools that manipulate and/or generate Parsetree values;
+`ppxlib.metaquot` which allows to construct Parsetree values using the
+OCaml syntax directly and `ppxlib.traverse` which provides various
+ways of automatically traversing values of a given type, in particular
+allowing to inject a complex structured value into generated code.
