One side-condition that has also changed is the build platform: for the
various Poly/ML 5.6 Isabelle components it was still Ubuntu 10.04 LTS,
for current Poly/ML 5.7.1 test versions it is Ubuntu 12.04 LTS.
Sometimes there are problems in the C/C++ compiler that disappear over

component contains brief instructions how to operate on the included src
