+	<longdescription lang="en">MEL is a small (~500 loc) header-only C++11 library to parse strings into math expression objects that can be evaluated at runtime, by substituting symbols (e.g. x) by runtime values. It can be used, for example, to implement user-defined functions (UDF) in a larger code, in a self-contained way.</longdescription>
