-// This file provides the following:
-//
-// 1) VERIFY(), via DEBUG_ASSERT, from Brent Verner <brent@rcfile.org>.
-// This file is included in the various testsuite programs to provide
-// #define(able) assert() behavior for debugging/testing. It may be
-// a suitable location for other furry woodland creatures as well.
-//
-// 2) __set_testsuite_memlimit()
-// __set_testsuite_memlimit() uses setrlimit() to restrict dynamic memory
-// allocation. We provide a default memory limit if none is passed by the
-// calling application. The argument to __set_testsuite_memlimit() is the
-// limit in megabytes (a floating-point number). If _GLIBCPP_MEM_LIMITS is
-// not #defined before including this header, then no limiting is attempted.
-//
-// 3) gnu_counting_struct
-// This is a POD with a static data member, gnu_counting_struct::count,
-// which starts at zero, increments on instance construction, and decrements
-// on instance destruction. "assert_count(n)" can be called to VERIFY()
-// that the count equals N.
-//
-// 4) gnu_char, gnu_char_traits, abstract character classes and
-// char_traits specializations for testing instantiations.
