Bakedoc is a set of scripts and makefiles, written in Bash and PHP. They exist to help you get a multi-section document together, splice in generated images from Dotty and MSCGen, etc.
Navigate to the directory where you want to store the document, and run the
command /path/to/bakedoc/install. This will copy bakedoc into the directory
as well as bootstrap all the files needed. When it is done, all you need to
do is type make to generate your first PDF. Then start editing the files in
the source directory to edit your document.
