Pyrex is a powerful tool for connecting C and Python by creating a Python module consisting of compiled C files. However, building a complex Python module using Pyrex is no simple task. Each time a change is made, all source files must be re-compiled, and re-bundled, linking against various frameworks. Repeatedly performing these tasks can quickly become very time consuming.

Pyrex Builder provides a straight-forward interface which allows you to identify files (.c, .h, and .pyx), frameworks, and compiler flags needed for the module. From there, a single button click will preform all the compiling, linking, and bundling tasks automatically. The build settings can also be saved, and loaded later; further reducing time spent creating modules.
