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.
