Extending CIL with external features

type t = {

mutable fd_enabled : bool;
(*
The enable flag. Set to default value
*)
fd_name : string;
(*
This is used to construct an option "--doxxx" and "--dontxxx" that * enable and disable the feature
*)
fd_description : string;
(*
A longer name that can be used to document the new options
*)
fd_extraopt : (string * Stdlib.Arg.spec * string) list;
(*
Additional command line options. The description strings should usually start with a space for Arg.align to print the --help nicely.
*)
fd_doit : Cil.file -> unit;
(*
This performs the transformation
*)
fd_post_check : bool;
(*
Whether to perform a CIL consistency checking after this stage, if * checking is enabled (--check is passed to cilly). Set this to true if * your feature makes any changes for the program.
*)
