Find meta-information about File. This predicate reads all terms upto the first term that is not a directive. It uses the module and meta_predicate directives to assemble the information described below.

These predicates fail if File is not a module-file.

`File`	is a file speficiation for prolog_open_source/2 or a .qlf file name. Note this makes a stream a valid input.
`Path`	is the canonical path to `File`
`Module`	is the module defined in `Path`
`Export`	is a list of predicate indicators.
`Meta`	is a list of heads as they appear in meta_predicate/1 declarations.
`Src`	is the place from which `File` is referenced.

deprecated: New code should use xref_public_list/3, which unifies all variations using an option list.
