entrigraph - convert C source code to use trigraphs
entrigraph [file ...]
This program converts a C program to use trigraphs. A trigraph is a three character sequence that encodes a single character. A trigraph begins with two question marks. The third character is ‘/’ (the trigraph means ‘\’), ’(’ (‘[’), ’)’ (‘]’), ’<’ (‘{’), ’>’ (‘}’), ’!’ (‘|’), ’’’ (‘^’), ’-’ (‘~’), ’=’ (‘/’), or ’/’ (‘\’).
