val split_path : string -> string list

split_path path splits path according to the PATH-splitting conventions of the platform. On Unix, this is exactly String.split_on_char ':' path. On Windows, entries are separated by semicolons. Sections of entries may be double-quoted (which allows semicolons in filenames to be quoted). The double-quote characters are stripped (i.e. f"o"o = foo; also split_path "foo\";\";bar" = ["foo;"; "bar"])

val preload_objects : string list ref

List of compilation units to be loaded before entering the interactive loop.

val prepare : Stdlib.Format.formatter -> ?input:input -> unit -> bool

Setup the load paths and initial toplevel environment and load compilation units in preload_objects.
