Changes since 1.1: +0 -0 lines 

initial import of tre-0.8.0 into the external sources framework.

with many thanks to ville laurikari for writing tre in the first place
and for changing the licensing to a 2-clause bsd license; thanks also to
matthias-christian ott for his work on the google summer of code 2009
project.

this import brings the distribution to src/external - the reachover
