+// DESCRIPTION:
+// ~~~~~~~~~~~~
+//
+// This file tests the incomplete gamma function inverses 
+// gamma_p_inva and gamma_q_inva. There are two sets of tests:
+// 2) TODO: Accuracy tests use values generated with NTL::RR at 
+// 1000-bit precision and our generic versions of these functions.
+// 3) Round trip sanity checks, use the test data for the forward
+// functions, and verify that we can get (approximately) back
+// where we started.
+//
+// Note that when this file is first run on a new platform many of
+// these tests will fail: the default accuracy is 1 epsilon which
+// is too tight for most platforms.  In this situation you will 
+// need to cast a human eye over the error rates reported and make
+// a judgement as to whether they are acceptable.  Either way please
+// report the results to the Boost mailing list.  Acceptable rates of
+// error are marked up below as a series of regular expressions that
+// identify the compiler/stdlib/platform/data-type/test-data/test-function
+// along with the maximum expected peek and RMS mean errors for that
+// test.
+//
