description     A field theory approach to symbolic computer algebra
long_description \
        Cadabra is a computer algebra system for the manipulation       \
        of what could loosely be called tensorial expressions. It is    \
        aimed at, though not necessarily restricted to, theoretical     \
        high energy physicists. Because of its target audience, the     \
        program's interface, storage system and underlying philosophy   \
        differ substantially from other computer algebra systems.

# Invalid C++, ticket #33045
# Cannot use clang because xperm uses nested functions and
# variable sized arrays, both of which clang will never
# support.
# Silly llvm makes cadabra crash all over the place for
# no good reason, so that's out too.

# Furthermore, we cannot use anything except 4.2 because
# that will lead to cadabra being linked to two different
# libstdc++ libraries, with malloc failures as a result.
