The filter is required to read from standard input, parse for error messages
and copy the error messages to the standard output.
During the output process, the filter must present the error messages in
- a format that LyX can interpret, currently, the LaTeX error message format.
- Of course, nothing will prevent future LyX releases from being able to
- read other formats as well (like gcc error messages for example).
