Yoink Win32 Dependencies
Created `date +"%d %b %Y"`

These dependencies were generated automatically by makedeps.sh, a script
available in the Yoink repository.  You should find here all the header
files, DLL's, implibs, and pkgconfig files required to build Yoink that are
not provided with the standard mingw32 toolchain.  Yoink itself can be
built with mingw32 and these installed dependencies like this:

./configure --host=$HOST --prefix=$PREFIX \\
            PKG_CONFIG_PATH=$PREFIX/lib/pkgconfig
make && make package

These files are licensed such that their general distribution under
reasonable conditions is allowable.  The copyrights of these binaries go to
their various respective owners.  Look up the specific library for specific
terms and conditions, or see the file COPYING in the Yoink package.
