- *
- * \subsection about About the BLI module
- *
- * This is the external interface of the Blender Library. If you find
- * a call to a BLI function that is not prototyped here, please add a
- * prototype here. The library offers mathematical operations (mainly
- * vector and matrix calculus), an abstraction layer for file i/o,
- * functions for calculating Perlin noise, scan-filling services for
- * triangles, and a system for guarded memory
- * allocation/deallocation. There is also a patch to make MS Windows
- * behave more or less Posix-compliant.
- *
- * \subsection issues Known issues with BLI
- *
- * - blenlib is written in C.
- * - The posix-compliance may move to a separate lib that deals with
- *   platform dependencies. (There are other platform-dependent
- *   fixes as well.)
- * - The file i/o has some redundant code. It should be cleaned.
- *
- * \subsection dependencies Dependencies
- *
- * - The blenlib uses type defines from \ref DNA, and functions from
- * standard libraries.
