I'm having a hard time seeing much use for this module, except as an object-oriented (and possibly platform-independent?) means of getting file information. In which case, the name is completely deceiving: it does no munging (manipulation) whatsoever of the file or attributes. (Admittedly File::Info etc. is already taken, but "Munger" is the wrong name.)
The current version (0.02) does not provide any features not already available in the Perl core. Useful things like file type, information relevant to the file type (e.g. image properties or character sets for text files or version information) etc. is not available, nor is platform-independent file information (such as pathnames).
The documentation does say more features would be added. It would be nice to know what the "master plan" of the module is.
