Main etry point to the sysinit component, all other modules are private.

The following API shoud be called in order, and the first 3 steps only once since they initialize global data. On the contrary step 4 can be called many times to init the compilation of a unit.

val init_ocaml : unit -> unit

1 initialization of OCaml's runtime

Profiling, GC parameters and signals. Nothing specific to Coq per se, but the defaults here are good for Coq. This API should be called up very early, or not at all.

val parse_arguments : parse_extra:(string list -> 'a * string list) -> usage:Usage.specific_usage -> ?initial_args:Coqargs.t -> unit -> Coqargs.t * 'a

2 parsing of Sys.argv

This API parses command line options which are known by Coq components. Ideally it is functional, but some values in the `Flags` modules are set on the spot instead of being represented as "injection commands" (a field of Coqargs.t).

parse_extra and usage can be used to parse/document more options.

val init_runtime : Coqargs.t -> Coqargs.injection_command list

3 initialization of global runtime data

All global setup is done here, like COQLIB and the paths for native compilation. If Coq is used to process multiple libraries, what is set up here is really global and common to all of them.

The returned injections are options (as in "Set This Thing" or "Require that") as specified on the command line. The prelude is one of these (unless "-nois" is passed).

This API must be called, typically jsut after parsing arguments.

val start_library : top:Names.DirPath.t -> Coqargs.injection_command list -> unit

4 Start a library (sets options and loads objects like the prelude)

Given the logical name top of the current library and the set of initial options and required libraries, it starts its processing (see also Declaremods.start_library)
