ReadMe_DeDRM_v5.5.3_WinApp
========================
DeDRM_v5.5_WinApp is a pure python drag and drop application that allows users to drag and drop ebooks or folders of ebooks onto the DeDRM_Drop_Target to have the DRM removed. It repackages all the "tools" python software in one easy to use program that remembers preferences and settings.
