+This is a collection of stopgap replacements for standard math
+functions missing from libm in various supported versions of
+FreeBSD. The functions are slower than the existing libm
+functions, but are more accurate than many naive replacements.
+Exceptions are largely ignored.  N. Beebe's extended C version
+of the ELEFUNT package is used to provide regression tests for
+some of the real-valued functions.
