[Virgil] Virgil B-03 Released

[Benjamin Titzer]

Hello Everyone,

Today is a great day in Virgil history. I've completed the third release 
of the Virgil language and compiler system and posted it on the website:

http://compilers.cs.ucla.edu/virgil

This release incorporates numerous bugfixes and feature enhancements, 
including:

- Many compiler bugs fixed
- More uniform semantics on AVR (int is now uniformly 32-bit)
- Better space optimizations
- More thorough command-line help
- Radically simplified and improved compiler interface
- Access to the built-in interpreter from the command line
   (now you can test and debug your programs right in the interpreter!)
- Preliminary support for parametric types (generics)

This release also comes with a new tutorial on the webpage that goes over 
the basics of all the language features step by step, explaining their 
syntax and semantics.

This release also contains a number of new example applications that run 
directly on the AVR microcontroller and can be simulated with Avrora.

Have a great day,
Ben L. Titzer
