+Description: Rust systems programming language - Documentation
+ 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.
+ .
+ It supports a mixture of imperative procedural, concurrent actor,
+ object-oriented and pure functional styles.  Rust also supports
+ generic programming and meta-programming, in both static and dynamic
+ styles.
+ .
+ This package contains sources of the rust standard library.
