+LibTomMath is a free open source portable number theoretic multiple-precision 
+integer library written entirely in C. (phew!). The library is designed to 
+provide a simple to work with API that provides fairly efficient routines that 
+build out of the box without configuration.
+
+The library builds out of the box with GCC 2.95 [and up] as well as Visual C++ 
+v6.00 [with SP5] without configuration. The source code is arranged to make it 
+easy to dive into a particular area very quickly. The code is also littered with 
+comments [This is one of the on going goals] that help explain the algorithms and 
+their implementations. Ideally the code will serve as an educational tool in the 
+future for CS students studying number theory.
+
+The library provides a vast array of highly optimized routines from various 
+branches of number theory.
+
+    * Simple Algebraic
+          o Addition
+          o Subtraction
+          o Multiplication
+          o Squaring
+          o Division 
+    * Digit Manipulation
+          o Shift left/right whole digits (mult by 2b by moving digits)
+          o Fast multiplication/division by 2 and 2k for k>1
+          o Binary AND, OR and XOR gates 
+    * Modular Reductions
+          o Barrett Reduction (fast for any p)
+          o Montgomery Reduction (faster for any odd p)
+          o DR Reduction (faster for any restricted p see manual)
+          o 2k Reduction (fast reduction modulo 2p - k)
+          o The exptmod logic can use any of the four reduction algorithms when 
+appropriate with a single function call. 
+    * Number Theoretic
+          o Greatest Common Divisor
+          o Least Common Multiple
+          o Jacobi Symbol Computation (falls back to Legendre for prime moduli)
+          o Multiplicative Inverse
+          o Extended Euclidean Algorithm
+          o Modular Exponentiation
+          o Fermat and Miller-Rabin Primality Tests, utility function such as 
+is_prime and next_prime 
+    * Miscellaneous
+          o Root finding over Z
+          o Pseudo-random integers
+          o Signed and Unsigned comparisons 
+    * Optimizations
+          o Fast Comba based Multiplier, Squaring and Montgomery routines.
+          o Montgomery, Diminished Radix and Barrett based modular 
+exponentiation.
+          o Karatsuba and Toom-Cook multiplication algorithms.
+          o Many pointer aliasing optimiztions throughout the entire library.
