That is very kind of you.

I've added some tests here:

I've written a simple bash shell script to handle must-fail tests.
The testsuite isn't complete, but it is a decent start. It is fairly
self-explanatory if you have a bash shell. Just:

$ ./test

(assuming permissions translate in the zip). One may have to:

$ chmod 755 test

first. Oh, and you'll have to change:

INCLUDE="-I/Users/hinnant/Development/boost-dev/boost-trunk -I.."

to point to your boost installation.
