<!-- directory layout for this build:

+- src
+- grammar
+- classes

+- javadoc
Move the grammar files into the grammar directory and
Main.java into the src directory before starting the build.
The following properties reflect this hierarchy.

<!-- the src directory in this example -->
<property name="src" location="src"/>
<!-- name of the package -->
<property name="package" value=""/>
<!-- where to write/find token files -->
<property name="token.lib" location="${src}/${package}" />
<!-- where to find the grammar files
in this example the grammar file is placed in the source
directory. Some people might prefer to locate it in a
separate directory, e.g. grammar directory.
To do so, just change
location="${src}" into
location="grammar"
if you like.

PolyPrinter.g depends from

- PolyDifferntiator.g depends from
- Poly.g
Note that Antlr is only invoked when necessary, e.g.
changes in PolyDifferentiator.g do not result in
Poly.g being recompiled. Only Simplifier.g and
PolyPrinter.g might be affected.
Call "ant" without parameters twice and you will
notice that no compilation by Antlr is done.
