 46//   ASSERT_PRED_FORMAT1(pred_format, v1)
 47//   ASSERT_PRED_FORMAT2(pred_format, v1, v2)
 48//   ...
 49//
 50// where pred_format is a function or functor that takes n (in the
 51// case of ASSERT_PRED_FORMATn) values and their source expression
 52// text, and returns a testing::AssertionResult.  See the definition
 53// of ASSERT_EQ in gtest.h for an example.
 54//
 55// If you don't care about formatting, you can use the more
 56// restrictive version:
 57//
 58//   ASSERT_PRED1(pred, v1)
 59//   ASSERT_PRED2(pred, v1, v2)
 60//   ...
 61//
 62// where pred is an n-ary function or functor that returns bool,
 63// and the values v1, v2, ..., must support the << operator for
 64// streaming to std::ostream.
 65//
 66// We also define the EXPECT_* variations.
 67//
 68// For now we only support predicates whose arity is at most 5.
 69// Please email googletestframework@googlegroups.com if you need
 70// support for higher arities.
