  * This library was released in public domain by Tom St Denis.

- * The combination in this file is not using many of the optimized algorithms
- * (e.g., Montgomery reduction) and is considerable slower than the LibTomMath
- * with its default of SC_RSA_1 settins. The main purpose of having this
- * version here is to make it easier to build bignum.c wrapper without having
- * to install and build an external library. However, it is likely worth the
- * effort to use the full library with SC_RSA_1 instead of this minimized copy.
- * Including the optimized algorithms may increase the size requirements by
- * 15 kB or so (measured with x86 build).
