latex warning output

To make latex print an warning at output one can use:

• \@latex@warning{My message}prints "file.tex:10: My message on input line 10"
• \@latex@warning@no@line{My message}prints "file.tex:0: My message"

One can define a \todo command to get warnings about uncompleted sections. The following todo command will print a

TODO...

in the PDF and the warning message passed as a parameter \todo{Finish Thanks section!}

Code for pasting in LaTeX package(.sty file)

\makeatletter
\newcommand{\todo}[1][]{\@latex@warning{TODO #1}\fbox{TODO\dots}}
\makeatother
