+synopsis: "Standard library for ppx rewriters"
+description: """
+Ppxlib is the standard library for ppx rewriters and other programs
+that manipulate the in-memory reprensation 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.
