What options exist to evaluate the software?

There are two options for evaluating the software:

Anonymously with a non-time-limited, but functionally restricted test version. The test version can be installed from the following Eclipse update site: http://www.pluginsmithy.com/demo_update_site/
After registration with a fully functional test version. Click here in order to register for a test version.

What are the restrictions in the test version that can be installed without registration?

In the Annotate Add-On you will only see a certain portion of the original text of an annotated file, the rest is obfuscated with a repeating text. Also only the first comment from the element history will be readable, the rest of the comments is obfuscated.

What are the restrictions in the test version that can be installed after registration?

The test version that can be downloaded after registration is functionally identical with the full version, but it will only work for 30 days starting from the time of the registration.
