 ### Build system
 
 * [Cargo](http://crates.io/) — the Rust package manager
+  * [rsolomo/cargo-check](https://github.com/rsolomo/cargo-check) - a wrapper around `cargo rustc -- -Zno-trans` which can be helpful for running a faster compile if you only need correctness checks [<img src="https://travis-ci.org/rsolomo/cargo-check.svg?branch=master">](https://travis-ci.org/rsolomo/cargo-check)
+  * [kbknapp/cargo-count](https://github.com/kbknapp/cargo-count) - lists source code counts and details about cargo projects, including unsafe statistics [<img src="https://travis-ci.org/kbknapp/cargo-count.svg?branch=master">](https://travis-ci.org/kbknapp/cargo-count)
+  * [maxsnew/cargo-dot](https://github.com/maxsnew/cargo-dot) - Generate graphs of a Cargo project's dependencies [<img src="https://travis-ci.org/maxsnew/cargo-dot.svg?branch=master">](https://travis-ci.org/maxsnew/cargo-dot)
+  * [killercup/cargo-edit](https://github.com/killercup/cargo-edit) - allows you to add and list dependencies by reading/writing to your Cargo.toml file from the command line [<img src="https://travis-ci.org/killercup/cargo-edit.svg?branch=master">](https://travis-ci.org/killercup/cargo-edit)
+  * [kbknapp/cargo-outdated](https://github.com/kbknapp/cargo-outdated) - displays when newer versions of Rust dependencies are available, or out of date [<img src="https://travis-ci.org/kbknapp/cargo-outdated.svg?branch=master">](https://travis-ci.org/kbknapp/cargo-outdated)
+  * [DanielKeep/cargo-script](https://github.com/DanielKeep/cargo-script) - lets people quickly and easily run Rust "scripts" which can make use of Cargo's package ecosystem
 * CMake
   * [SiegeLord/RustCMake](https://github.com/SiegeLord/RustCMake) — an example project showing usage of CMake with Rust [<img src="https://travis-ci.org/SiegeLord/RustCMake.svg?branch=master">](https://travis-ci.org/SiegeLord/RustCMake)
 * [clog-tool/clog-lib](https://github.com/clog-tool/clog-lib) — a library for generating a changelogs from git metadata [<img src="https://travis-ci.org/clog-tool/clog-lib.svg?branch=master">](https://travis-ci.org/clog-tool/clog-lib)
