-dumpast
--------
-
-This tool parses fragments of OCaml code (or entire source files) and
-dump the resulting internal Parsetree representation.  Intended uses:
-
- - Help to learn about the OCaml Parsetree structure and how it
-   corresponds to OCaml source syntax.
-
- - Create fragments of Parsetree to be copy-pasted into the source
-   code of syntax-manipulating programs (such as ppx rewriters).
-
-Usage:
-
-    ocamlfind ppx_tools/dumpast -e "1 + 2"
-
-The tool can be used to show the Parsetree representation of small
-fragments of syntax passed on the command line (-e for expressions, -p
-for patterns, -t for type expressions) or for entire .ml/mli files.
-The standard -pp and -ppx options are supported, but only applied on
-whole files.  The tool has further option to control how location and
-attribute fields in the Parsetree should be displayed.

-genlifter
----------
-
-This tool generates a virtual "lifter" class for one or several OCaml
-type constructors.  It does so by loading the .cmi files which define
-those types.  The generated lifter class exposes one method to "reify"
-type constructors passed on the command-line and other type
-constructors accessible from them.  The class is parametrized over the
-target type of the reification, and it must provide method to deal
-with basic types (int, string, char, int32, int64, nativeint) and data
-type builders (record, constr, tuple, list, array).  As an example,
-calling:
-
-    ocamlfind ppx_tools/genlifter -I +compiler-libs Location.t
-
-produces the following class:
-
-    class virtual ['res] lifter =
-      object (this)
-        method lift_Location_t : Location.t -> 'res=
-          fun
-            { Location.loc_start = loc_start; Location.loc_end = loc_end;
-              Location.loc_ghost = loc_ghost }
-             ->
-            this#record "Location.t"
-              [("loc_start", (this#lift_Lexing_position loc_start));
-              ("loc_end", (this#lift_Lexing_position loc_end));
-              ("loc_ghost", (this#lift_bool loc_ghost))]
-        method lift_bool : bool -> 'res=
-          function
-          | false  -> this#constr "bool" ("false", [])
-          | true  -> this#constr "bool" ("true", [])
-        method lift_Lexing_position : Lexing.position -> 'res=
-          fun
-            { Lexing.pos_fname = pos_fname; Lexing.pos_lnum = pos_lnum;
-              Lexing.pos_bol = pos_bol; Lexing.pos_cnum = pos_cnum }
-             ->
-            this#record "Lexing.position"
-              [("pos_fname", (this#string pos_fname));
-              ("pos_lnum", (this#int pos_lnum));
-              ("pos_bol", (this#int pos_bol));
-              ("pos_cnum", (this#int pos_cnum))]

-_dumpast_ is a direct example of using _genlifter_ applied on the
-OCaml Parsetree definition itself.  ppx_metaquot is another
-similar example.
