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