Note: If you plan to use LTemplate, please send me an email and let me know about your use case. If I know how people use it, I can be more careful with breaking changes.
To install, drop the
LTemplate directory in the directory opened by
Documentation/LTemplateTutorial.nb for a short introduction through examples.
skeleton-project directory contains a sample project that embeds LTemplate. Use this as a starting point for your own LTemplate-based package.
For an example of an application that uses and embeds LTemplate, see IGraph/M.
