### Java Climate Model Package Info

This is a package of JAR (Java Archive) files needed to run Java Climate Model Note that the preferred way to open JCM is to launch it from the website using Java Webstart, as this checks automatically for updates.

Most documentation is included within the model, but some extra documentation (with external links) is only on the website.
