+# This file is supposed to implement error reporting for Boost.Build.
+# Experience with jam version has shown that printing full backtrace
+# on each error is buffling. Further, for errors printed after parsing --
+# during target building, the stacktrace does not even mention what
+# target is being built.
+
+# This module implements explicit contexts -- where other code can
+# communicate which projects/targets are being built, and error
+# messages will show those contexts. For programming errors,
+# Python assertions are to be used.
