Ruby library for read/write access for OLE compound documents

 Ruby-ole is a library for read/write access to OLE2 structured storage
 files, such as those produced by Microsoft Office, eg *.doc, *.msg
 etc.
 .
 It provides a simple and easy to use API, supporting read and write
 streaming, by providing transparent access to the "files" within OLE
 documents as IO-like objects, supporting all the expected operations.
