  Description     : TomsFastMath is a fast large integer arithmetic library.

It is a port of LibTomMath with optional support for inline assembler multipliers.
It has the following features:

- Public domain, open source and freely accessible
- Builds with GCC [preferably v3.3.x or higher] on any 32-bit/64-bit box
- Includes ASM optimizations (inline) for
  - x86-32 (e.g. i386 and SSE2)
  - x86-64 (e.g. AMD64)
  - ARM (ARMv4 and higher)
  - PPC32 (e.g. G3/G4)
  - PPC64 (e.g. G5)
  - AVR32 (Atmel 32-bit RISC processor)
  - MIPS (32-bit)
- Includes fairly complete API (provides most of what LibTomMath provides)
- Uses similar API as LibTomMath makes porting easy
- Competitive speeds (and getting higher).
  - Faster than OpenSSL on the AMD64
  - Still room for improvements
- No heap usage (malloc/calloc/free)
- Uses only inline asm, simplifies build process, simple to add new ports

This library is already used by a few application in the Debian archive
which use a copy of this library within their source tree. I noticed
this in the clamav package. Debian's code search [0] reveals other
packages.
