/*
 * Here provide a series of helpers in the str_$TRUE_$FALSE format (you can
 * also expand some helpers as needed), where $TRUE and $FALSE are their
 * corresponding literal strings. These helpers can be used in the printing
 * and also in other places where constant strings are required. Using these
 * helpers offers the following benefits:
 *  1) Reducing the hardcoding of strings, which makes the code more elegant
 *     through these simple literal-meaning helpers.
 *  2) Unifying the output, which prevents the same string from being printed
 *     in various forms, such as enable/disable, enabled/disabled, en/dis.
 *  3) Deduping by the linker, which results in a smaller binary file.
