The code is designed to be portable to any Unix-like operating system. Coot certainly runs on SGI IRIX64, RedHat Linux of various sorts, SuSe Linux1 and MacOS X (10.2). The sgi Coot binaries should also work on IRIX.
If you want to port to some other operating system, you are welcome 2. Note that your task will be eased by using GNU GCC to compile the programs components.
Coot works best with a 3-button mouse and works better if it has a scroll-wheel too (see Chapter 2 for more details) 3.
