32 /** The packages and commands that a buffer needs. This class
33 * contains a list<string>. Each of the LaTeX packages that a buffer needs
34 * should be added with void require(string const & name).
36 * i.e require("amssymb")
38 * To add support you should only need to require() the package name as
39 * packages which don't have special requirements are handled automatically.
40 * If your new package does need special consideration you'll need to alter
41 * string const getPackages() const;
42 * Remember to update the validate function in Buffer.cpp and Paragraph.cpp
