/**
This task compiles Visual Basic.NET source into executables or modules.
The task will only work on win2K until other platforms support vbc.exe or 
an equivalent. VBC.exe must be on the execute path too.

<p>
All parameters are optional: &lt;vbc/&gt; should suffice to produce a debug
build of all *.vb files.
