Crun is an utility for compiling and running C-programs straight from C source files. Crun supports compile-run and compile-debug flows. You can embed custom compile options into the main c-file, if you need, for example, an external library for the program.

Diru is a Change Directory (cd) utility for augmenting Unix Shell functionality. Diru makes it easy and efficient to jump around in Project's directories. Diru uses client/server architecture, which enables sharing of directory info and state between terminal sessions. Each Server serves one Project, which is a tree of related directories where user wants to jump around and which has a logical root. There can be multiple Servers, if user needs to access multiple Projects concurrently. Client queries directory info from Server and directory change is pushed to Shell in order to change the current directory within the Shell.

Rumodule is used to manage shell environment variables by adding/removing modules.

Rumodule makes it easy to maintain and provide tool setups between multiple users.
