OK. I got pnetlib, pnet, and treecc. Im trying to compile treec but when I make it, I get this error:

% make all
cd . && aclocal
cd . && automake --gnu Makefile
automake: required file `./depcomp' not found
make: *** [] Error 1

I downloaded treecc from southern-storm on the downloads page.
Oh ya, and BTW, Im using OSX. Not that it _should_ technically matter. It ./configured :)

I don't understand the return objA.Equals(objB), but I probably would if I

The ECMA specification describes how this method
should work.

Every object has a virtual "Equals(Object obj)" method
for comparing the "this" object against some other object.
Subclasses override this method to provide particular
equality testing algorithms.  Check out classes like
"Int32", "String", and "Version" for examples.

The static "Equals" method wraps this up to provide a
more convenient way of saying "objA is equal to objB",
without having to worry about the "null" cases, or the
common case of objA and objB being the same object.

I would really like to know exactly what methods will be available from
the runtime so I can use them when making libraries.  Maybe one of the
senior members of this list can help me out.

The C# language provides the basics ("if", "while", etc),
and pnetlib provides the rest.  Sometimes it is necessary
to drop down to the runtime engine to perform some task
that cannot be expressed in C# (e.g. Object.GetType).
These facilities are provided with "InternalCall" methods.

These cases are fairly rare.  Most of the time, what you
need is already available in the existing classes.  And the
ECMA specification documents what they should do.
