Notes on use

CCFSW performs lexical analysis, but does not have separate lexical analysis mechanisms for each language.
CCFSW performs lexical analysis tailored to each language by using optional files.
(At the same time, this does not mean that the lexer algorithm is optimized for each language.)
This option file can be modified by the user.
Refer OptionFile.md for the notation of the option file.
