Module: FileTest

Relationships & Source Files
Defined in: file.c,

FileTest implements file test operations similar to those used in ::File::Stat. It exists as a standalone module, and its methods are also insinuated into the ::File class. (Note that this is not done by inclusion: the interpreter cheats).
