+Enforcing Compile-time Format Checks
+------------------------------------
+To force the use of Compile-time checks, compile with 
+``FMT_ENFORCE_COMPILE_STRING`` defined. When this preprocessor definition is

+strings. When this is set, runtime-checked formatting is still possible using
+``fmt::vformat``, ``fmt::vprint``, etc.
