This is very much appreciated but I find Travis CI just confusing in the
difficulty of specifying what compilers/versions should be run on which
OSs, and what is actually available to test. I can of course try to work
with the travis.yml in the link above. There are now your .travis.yml,
Bruno's .travis.yml based on your original solution using boostdep, and
Rene's solution. I appreciate everything everyone has done but I feel I
will be spending too much time on a product ( Travis CI ) for which I
understand little, which is difficult to use, and whose documentation is
appalling. I just have better things to do ( like programming <g> ) than
to joust with Travis CI. I understand of course that is is "free" but I
don't see it as a good solution to continuous testing.
