The Sollya software is a computer program whose purpose is to provide
an environment for safe floating-point code development. It is
particularly targeted to the automated implementation of
mathematical floating-point libraries (libm). Amongst other features,
it offers a certified infinity norm, an automatic polynomial
implementer and a fast Remez algorithm.

therefore means that it is reserved for developers and experienced
professionals having in-depth computer knowledge. Users are therefore
encouraged to load and test the software's suitability as regards
their requirements in conditions enabling the security of their

you may (at your option) remove this special exception, which will
cause this generated code and its skeleton and the resulting Sollya
