Compilation
===========

To recompile, you need Microsoft Visual C++ 6.0. Just
double click the davplug.dsw file, then build the project.
The plugin wfx file will always be placed in the wfx
subdir, both for the Debug and Release versions, so it's
not necessary to redefine the location of the plugin
to test both.
