+// This is the main entry point for our operator performance test suite.
+// In order to build this program, you must compile and link this file against
+// all the libs/multiprecision/performance/performance_test_files/*.cpp files.
+// 
+// The default behaviour is to "test everything", which is probably not what you want.
+// In order to restict testing to a specific selection of backends, you will need to
+// define one or more of the following macros when building:
+// 
+// TEST_MPF
+// TEST_MPZ
+// TEST_CPP_DEC_FLOAT
+// TEST_MPFR
+// TEST_MPQ
+// TEST_TOMMATH
+// TEST_TOMMATH_BOOST_RATIONAL
+// TEST_MPZ_BOOST_RATIONAL
+// TEST_CPP_INT
+// TEST_CPP_INT_RATIONAL
+// TEST_CPP_BIN_FLOAT
