# travis currently does not support directly setting gcc/clang with versions
# (e.g. gcc-4.8) as value for the compiler key. So we will have to manually
# request these packages and use environment varibles to create the matrix.
#
# In the case of osx, use brew to install the paritcular versions, instead of
# specifying with packages.
