Camomile is a Unicode library for OCaml, also known as Objective Caml or O'Caml. Its interface files contain compiled information that the OCaml toolchain uses when working with Camomile modules.
The library provides Unicode character types; UTF-8, UTF-16 and UTF-32 strings; conversion to and from about 200 encodings; collation; locale-sensitive case mappings; and related functionality.
A cmi file belongs to the compiled Camomile library and supports the use of its modules in OCaml programs. The Camomile software linked to this file type runs on Microsoft Windows. The file is an implementation detail of the library rather than a general-purpose data-exchange format.
Camomile uses cmi files internally when OCaml programs refer to its modules. They are normally found in the Camomile installation or a compiled OCaml project and are not opened as standalone documents.
On Microsoft Windows, use the OCaml development tools together with Camomile to use the file. A text editor can display its contents only as unintelligible compiled data.
Conversion of cmi files to other formats is not possible. They contain compiled interface data for the OCaml toolchain.
If a different cmi file is needed, rebuild the relevant Camomile or OCaml project from its source files instead of converting the existing file.
