API Cool Reader

There is a Cool Reader engine available for programmers who wish to write their own user interface. CREngine is an open source E-Book viewer library development project. It's partially based on CoolReader2 e-book viewer code, but most parts of code are fully rewritten. The goal is to develop small and fast e-book viewer for mobile devices as well as for desktops. Priority is given to low memory and CPU resource requirements.

The API is available in Source file form and also for Windows, MacOS X, and Linux.
