-VER 2.2: NEW API:

-void        print(fmt, ...);

-void        println(fmt, ...);

-void        printd(dest, fmt, ...);

-

-void        fmt_print(fmt, ...);

-void        fmt_println(fmt, ...);

-void        fmt_printd(dest, fmt, ...);

-void        fmt_close(fmt_stream* ss);

-

-  dest - destination, one of:

-    FILE* fp        Write to a file

-    char* strbuf    Write to a pre-allocated string buffer

-    fmt_stream* ss  Write to a string-stream (auto allocated).

-                    Set ss->overwrite=1 for overwrite-mode.

-                    Call fmt_close(ss) after usage.

-

-  fmt - format string

-    {}              Auto-detected format. If :MOD is not specified,

-                    float will use ".8g" format, and double ".16g".

-    {:MODS}         Format modifiers: '<' left align (replaces '-'). Default for char* and char.

-                                      '>' right align. Default for numbers.

-                    Other than that MODS can be regular printf() format modifiers.

-    {{  }}  %       Print the '{', '}', and '%' characters.

-

-* C11 or higher required.

-* MAX 255 chars fmt string by default. MAX 12 arguments after fmt string.

-* Define FMT_IMPLEMENT or i_implement prior to #include in one translation unit.

-* Define FMT_SHORTS to define print(), println() and printd() macros, without fmt_ prefix.
