-Rust
+Rust is a systems programming language that runs blazingly fast,
+prevents segfaults, and guarantees thread safety.
 
-Rust is a curly-brace, block-structured expression language.
+https://www.rust-lang.org
 
-It visually resembles the C language family, but differs significantly
-in syntactic and semantic details.
+This will build rust from source, which requires using the "official" stage0
+compiler for the version being built from rust-lang.org. Currently, "official"
+means the previous stable version.
 
-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.
+If you already have rust and cargo installed, this slackbuild will use these to
+bootstrap itself.
 
-It supports a mixture of imperative procedural, concurrent actor,
-object-oriented and pure functional styles. Rust also supports generic
-programming and metaprogramming, in both static and dynamic styles.
+You can also force either behaviour through the LOCAL_BOOTSTRAP=yes|no
+parameter.
 
-Cargo - the Rust package manager - is included in this build.
-
-A short summary of features:
-
-Type system: static, nominal, linear, algebraic, locally inferred
-
-Memory safety: no null or dangling pointers, no buffer overflows
-
-Concurrency: lightweight tasks with message passing, no shared memory
-
-Generics: type parameterization with type classes
-
-Exception handling: unrecoverable unwinding with task isolation
-
-Memory model: optional task-local GC, safe pointer types with region analysis
-
-Compilation model: ahead-of-time, C/C++ compatible
-
-License: dual MIT / Apache 2
