utility to extract a name from a PPI Document
PPIx::DocumentName contains a few utilities for extracting a "name" out of an arbitrary Perl file. . Typically, this is the module name, in the form: . package Foo . However, it also supports extraction of an override statement in the form: . # PODNAME: OverrideName::Goes::Here . which may be more applicable for documents that lack a package statement, or the package statement may be "wrong", but they still need the document parsed under the guise of having a name (for purposes such as POD).
