no-herd Current focus of Ensymble development is to provide useful tools for making Python for S60 programs. Supported functions include generation of SIS (installation) packages, merging several SIS packages into one, (re-)signing existing SIS packages and modifying extension DLL headers. Support for other Symbian OS software development tasks will follow. A long term goal of Ensymble is to provide a cross-platform, open-source way to do Symbian OS software development, supporting Symbian OS versions 9.1 and later. The original tools by Symbian are closed source and only available for the Windows® operating system.
