files have to be unique for Android, about.html from various .jars clash when assembled for Android because they have the same name and the same content. except if they are located in META-INF. However a tool from David searches the .jars from the release train that all about.html files are in the root of the .jar bundles
suggestion from Glyn, put about.html per default in the root of the .jar and allow a header in the MANFEST.MF to point to a different location in the .jar i.e. in the META-INF directory
