check for trigraphs in C source code
SYNOPSIS
chktri [file ...]
DESCRIPTION
This program looks for lines containing trigraphs in C source code.
Trigraphs are a way to represent certain characters
in C source code as two question marks and a third character.
For example, a backslash could be represented as `??/'.
For a detail specification, see section 5.2.1.1 in the
ISO 9899:1990 standard or any decent C book.
(You don't really want to know.)
