+description         A safe, concurrent, practical language
+long_description    Rust is a curly-brace, block-structured expression \
+                    language. It visually resembles the C language \
+                    family, but differs significantly in syntactic and \
+                    semantic details. Its design is oriented toward \
+                    concerns of “programming in the large”, that is, of \
+                    creating and maintaining boundaries – both abstract \
+                    and operational – that preserve large-system \
+                    integrity, availability and concurrency.
