Questions on POLE library (and HancomWord support)

[matus.uzak at gmail.com]

Hi,

compared to the latest version found at [1], the version of POLE inside
libmso includes a number of bug fixes and code to detect invalid and
corrupt files in the Windows Compound Binary File Format.  It's not
maintained as a separate library, It's simply part of libmso.  And you
should know it's fine tuned to files produced by MS Office, so it might be
required to disable a bunch of blocks of code.

In Calligra, libgsf has been superseded by libmso.

Check the powerpoint or msword-odf filter for proper usage.  Look for the
readStream function in the mswordodfimport.cpp file, which reads a stream
from a specific storage into a buffer.
