(** cmt and cmti files format. *)

|
|
|
(** The layout of a cmt file is as follows:
|
|
<cmt> := \{<cmi>\} <cmt magic> \{cmt infos\} \{<source info>\}
|
|
where <cmi> is the cmi file format:
|
|
<cmi> := <cmi magic> <cmi info>.
|
|
More precisely, the optional <cmi> part must be present if and only if
|
|
the file is:
|
|
- a cmti, or
|
|
- a cmt, for a ml file which has no corresponding mli (hence no
|
|
corresponding cmti).
|
|
|
|
Thus, we provide a common reading function for cmi and cmt(i)
|
|
files which returns an option for each of the three parts: cmi
|
|
info, cmt info, source info. *)
