CMM has all of the core features you would expect for creating new maps and editing existing ones, plus it has these more interesting functions:

• Scan a map image for unused areas and automatically generate territories in them
• Analyze a map image and automatically connect bordering territories (or find errors with existing border connections)
• Resize maps
• Rename all territories based on their continent names (e.g. "Asia 1", "Asia 2", etc.)
• Center selected territories within their borders (weighted average position)

You need a recent version of the Java runtime installed to use CMM. Java can be downloaded at www.java.com and is very easy to install. CMM itself is a single file (cmm.jar) and requires no installation. Once you have Java installed, you can run cmm.jar like any other executable--double click on it from an Explorer window, create shortcuts to it, run it from the command line, etc. It will create a configuration file and a log file in the directory you run it from.
