_DESCRIPTION = """\
MultiPL-E is a dataset for evaluating large language models for code \
generation that supports 18 programming languages. It takes the OpenAI \
"HumanEval" and the MBPP Python benchmarks and uses little compilers to \
translate them to other languages. It is easy to add support for new languages \
and benchmarks.
