+// Compiler/library version workaround macro
+//
+// Usage:
+//
+//     #if BOOST_WORKAROUND(BOOST_MSVC, < 1300)
+//        // workaround for eVC4 and VC6
+//        ... // workaround code here
+//     #endif
+//
+// When BOOST_STRICT_CONFIG is defined, expands to 0. Otherwise, the
+// first argument must be undefined or expand to a numeric
+// value. The above expands to:
+//
+//     (BOOST_MSVC) != 0 && (BOOST_MSVC) < 1300
+//
+// When used for workarounds that apply to the latest known version 
+// and all earlier versions of a compiler, the following convention 
+// should be observed:
+//
+//     #if BOOST_WORKAROUND(BOOST_MSVC, BOOST_TESTED_AT(1301))
+//
+// The version number in this case corresponds to the last version in
+// which the workaround was known to have been required. When
+// BOOST_DETECT_OUTDATED_WORKAROUNDS is not the defined, the macro
+// BOOST_TESTED_AT(x) expands to "!= 0", which effectively activates
+// the workaround for any version of the compiler. When
+// BOOST_DETECT_OUTDATED_WORKAROUNDS is defined, a compiler warning or
+// error will be issued if the compiler version exceeds the argument
+// to BOOST_TESTED_AT().  This can be used to locate workarounds which
+// may be obsoleted by newer versions.
