we will release jmove 0.2 this week - perhaps tomorrow if the new years 
party is not too exhausting ;-).

Release 0.2 is nearly a complete redesign compared to 0.1 with many 
functional extensions. As the release number indicates we are just at 
the beginning of the project and the work has been concentrated on the 
basic functionality.

At the moment jmove mainly provides an API which can be used for byte 
code and source code analysis. We think it is powerful and fairly easy 
to use. jmove analyses byte or source code and creates an model of the 
implementation. The model is defined by the API and is the basis for 
further analysis. So we use it in conjunction with junit to perform 
architecture and design tests. At the moment there are not command line 
or gui tools which produces some kind of architecture or metrics 
report. But i think such tools are not hard to implement and are a 
natural extension of jmove's current functionality.

To use the API you'll require the jmove jar created during the build ( 
build/libs/jmove.jar ).
To get an impression of how to use the API take a look at the classes 
in the org.jmove.examples.java package of the test case classes in the 
*.test packages. One of the next steps will be the improvement of the 
documentation. So long please take a look at our home page 
http://www.jmove.org and especially at our wiki 
http://www.jmove.org/cgi-bin/piki .


> One more question: which metrics are currently implemented?

There are few metrics which jmove currently provides via its API:

- The set of metrics defined by Robert. C. Martin  
(http://www.objectmentor.com/publications/oodmetrc.pdf)

- Lines of Code (only with source code analysis)

- Number of Classes

- Number of Packages

- Number of Members (only with source code analysis at the moment)

Implementing metrics is one of the main goals of the project. So on the 
one hand we will plan to implement more metrics and on the other hand 
we try to make it easy to implement new metrics for jmove 
users/contributers.

I hope this answer will help you a bit. If you have further questions 
just ask. For us it is also interesting to know more about your 
personal requirements. So it would be nice if you let us know what kind 
of metrics or other functionality you would like to find in jmove.


Happy new year

Axel
