My project writeup about the DSML Tools contains a general overview of the technologies,
a description of the software and detailed description of some of the key bits of code.
End User Documentation
README-src (Current source release).
README-bin (Current binary release).
Both of the above include the installation instructions, if you wish to review them before downloading a package.
There is currently no other user documentation - however, the help (the -? command line switch, or in the Javadoc,
or in the Functional Specification) should explain most things.
Known bug list
Javadoc for the DSML Tools codebase.
Functional Specification - also useful as a user manual of sorts.
Design Document - a very high-level guide to the internals.
However, the code is extremely well commented - the best thing to do if you want to hack on it is read the Javadoc,
then read the code itself.
