The options are formatted as follows:
- For most options, the option and the parameters are separated by a space as in "-xxx param".
When the option's name is "-xxx+", however, the parameter must directly follow the option, without the "+" character (as in "-xxx45") and with no space separator.
- An option given as "-[no]xxx" may be issued as "-xxx" or "-noxxx".
The use of "-noxxx" reverses the meaning of the option.
- When an option is specified as "-xxx | yy[y] | zzz", then either "-xxx", "-yy", "-yyy", or "-zzz" matches the option.
- The symbols "," and "=" separate options and parameters unconditionally; to include one of these symbols in a parameter or filename, escape it (e.g., as "\," in mwcc file.c\,v).
