This is a single GNU makefile that builds a LaTeX document into
various targets with minimal latex/bibtex invocations. It colorizes
and swallows the normally unhelpful latex output so that errors and
other important messages are easy to spot. It handles GNUplot, Fig,
and Dot image creation (and handles many more formats besides), and
does automatic dependency tracking.
Perhaps most important, it is convenient because it is a single file
and only depends on standard Unix utilities that are likely to exist
on any system. It includes built-in help documentation and various utilities to test whether it will work on your system.
