val declare: string -> (string -> unit) -> unit
(** Declare a parameterized tag.
[declare "name" action]: [action "param"] will be executed (once) by [init]
if a tag of the form [name(param)] is [acknowledge]d.
A given tag may be declared several times with different actions. All actions
will be executed, in the order they were declared. *)
val acknowledge: string -> unit
(** Acknowledge a tag.
If the tag is of the form [X(Y)], and have been declared using [declare],
then the actions given using [declare] will be executed with [Y] as parameter
when [init] is executed. The action will only be called once per
acknowledged parameter. *)
val init: unit -> unit
(** Initialize parameterized tags.
Call this function once all tags have been [declare]d and [acknowledge]d.
If you [declare] or [acknowledge] a tag after having called [init], this will
have no effect. [init] should only be called once. *)
val make: Tags.elt -> string -> Tags.elt
(** Make a parameterized tag instance.
Example: [make "package" "unix"]: return the tag ["package(unix)"] *)
