description     The Erlang Programming Language
long_description                                                        \
                Erlang is a programming language designed at the        \
                Ericsson Computer Science Laboratory. Open-source       \
                Erlang is being released to help encourage the spread   \
                of Erlang outside Ericsson.                             \
                                                                        \
                We are releasing free of charge:                        \
                    The entire source code of the current Erlang        \
                    system.                                             \
                    Extensive libraries of code for building robust     \
                    fault-tolerant distributed applications.            \
                    All with documentation.                             \
                                                                        \
                All the above software has been battle tested in a      \
                number of Ericsson products, for example the new        \
                Ericsson ATM switch.
