  * `CPLEX.jl` wraps the `CPLEX` library, which can be identified easily in a web search.
  * `MATLAB.jl` provides an interface to call the MATLAB engine from within Julia.

 7. Avoid naming a package closely to an existing package
  * `Websocket` is too close to `WebSockets` and can be confusing to users. Rather use a new name such as `SimpleWebsockets`.

+ A package name of `Tkinter.jl` would only be appropriate if the package used Python's
+ library to accomplish its work or was spearheaded by the same community of developers.

 ## Registering packages
 
 Once a package is ready it can be registered with the [General Registry](https://github.com/JuliaRegistries/General#registering-a-package-in-general) (see also the [FAQ](https://github.com/JuliaRegistries/General#faq)).
