There is for now a single tool in here called spfquery originally authored
by Wayne for his test suite.  I've made various changes to it but the long
and the short of it is, it remains here as a demonstration of the API.

Description of MAKE targets:
----------------------------

make         : makes spfquery object
make static  : makes spfquery binary linking statically
make shared  : makes spfquery binary linking dynamically
make clean   : removes binary and object files
make install : installs spfquery to /usr/local/bin
make test    : executes a test run (test.pl)

Here are some example uses of the spfquery tool.
