+  The Kani Rust Verifier is a bit-precise model checker for Rust. 
+  Kani is particularly useful for verifying unsafe code blocks in Rust, 
+  where the "unsafe superpowers" are unchecked by the compiler.
+  Kani verifies:
+  
+  * Memory safety (e.g., null pointer dereferences)
+  * User-specified assertions (i.e., assert!(...))
+  * The absence of panics (e.g., unwrap() on None values)
+  * The absence of some types of unexpected behavior (e.g., arithmetic overflows)
