It is not possible to add modules specifying a directory root name.
As it is described in EpyDoc documentation it should be possible to specify a package directory beside modules, .
In GUI there was not possible to add such a package directory, but only certain module(s) using "Browse".
Same wrong behavior was met using "config" file, where for "module: " it is not possible to specify a directory, just Python modules
If this is not considered as a BUG, then it could be considered a nice feature.
It should be possible to specify a root directory from where all python modules to be taken (including all sub-directories) and have to be documented.
I have used EpyDoc Windows installation kit and I'm running Windows XP.
