 Usage: `./build.sh` produces `*.o` static libraries (for distribution to others,) plus `a.out` to do unit tests (test harnesses). Allowed flags; `--debug` (default; includes frame-pointers/debug symbols (`-g`), includes `valgrind`-replacement tools (such as `-fsanitize=address`), `--release` (excludes `--debug`, strips frame-pointers/symbols, optimizes with `-O2`), `--mingw` (if on _Linux_, can use with `--release` or `--debug`, produces _Portable Executable_ for _Windows_. If on _Windows_, the default is to produce _Portable Executable_'s for _Windows_)
     Optional flags (`vim build.sh` to use):
-        `-DSUSUWU_USE_STDERR` to replace `std::cerr` with `fprintf(stderr, ...)`, default is `!defined(__cplusplus)`.
+        `-DSUSUWU_SH_RUNTIME_COLORS` to replace `#if ... #else ... #endif` with operating system calls to choose whether or not to use colors, default is undefined.
+        `-DSUSUWU_SH_STDERR` to replace `std::cerr` with `fprintf(stderr, ...)`, default is `!defined(__cplusplus)`.
         `-DSUSUWU_SH_SKIP_BRACKETS = true` sets output format to `WARN_LEVEL: message`, default is `false`.
         `-DSUSUWU_SH_FILE = true` sets output format to `[__FILE__: WARN_LEVEL: message]`, default is `!defined(NDEBUG)`.
         `-DSUSUWU_SH_LINE = true` sets output format to `[__LINE__: WARN_LEVEL: message]`, default is `!defined(NDEBUG)`.
