For the ANTLR3 neophytes amongst us, here are the steps Chris led me through
to get CVC4 to compile with this new ANTLR3 stuff:

1. Go to the ANTLR3 page and download Complete ANTLR 3.2 jar; all tools,
runtime, etc... <http://antlr.org/download/antlr-3.2.jar> to /path/to/antr3jar/
2. Download the attachment to Chris's email "antlr3" to /path/to/antlr3executable/
3. Open /path/to/antlr3executable/antlr3 in your favorite text editor and change the 3rd line to
   "export CLASSPATH=/usr/share/java/stringtemplate.jar:/path/to/antr3jar/antlr-3.2.jar"
4. Download "libantlr3c-3.2.tar.gz" from http://antlr.org/download/C and extract the archive to /path/to/libantr/src/
5. Enter /path/to/libantr/src/
6. If you are on a 32-bit machine, run "./configure --prefix=/path/to/libantlr3c/installation".
    If you are on a 64 bit machine, run "./configure --prefix=/path/to/libantlr3c/installation --enable-64bit".
    --prefix=PREFIX specifies the library installation directory. This defaults to "/usr/local"
7. make
8. [sudo] make install
9. cd /path/to/cvc4
10. Now run "./configure --with-antlr-dir=/path/to/libantlr3c/installation
ANTLR=/path/to/antlr3executable/antlr3"

--Tim

export CLASSPATH=/usr/share/java/stringtemplate.jar:/path/to/antr3jar/
