Language and OS support

From the beginning, Métamorphose was conceived to be as widely usable as possible. As a result of this, there has been extensive testing and adjustments done to ensure all portions of the application are displayed and function properly across different platforms. Here are the fully tested and supported operating systems:

• MS Windows, versions: 2000, XP, 2003 server, and Vista.
• Linux

Métamorphose 2

With the first version now completed, work for the next stage of the project has begun. More specifically, the focus is on fixing the following shortcomings of the current version:

• User has no control of order of operations.
• Only one operation type per rename.
• Main interface can be confusing to a new user.
• No way to make 3rd party add-on modules.
• Adding more user-requested features.
