// This file defines templates for transforming Modelica/MetaModelica code to FMU
// code. They are used in the code generator phase of the compiler to write
// target code.
//
// There are one root template intended to be called from the code generator:
// translateModel. These template do not return any
// result but instead write the result to files. All other templates return
// text and are used by the root templates (most of them indirectly).
//
// To future maintainers of this file:
//
// - A line like this
// # var = "" /*BUFD*/
// declares a text buffer that you can later append text to. It can also be
// passed to other templates that in turn can append text to it. In the new
// version of Susan it should be written like this instead:
// let &var = buffer ""
//
// - A line like this
// ..., Text var /*BUFP*/, ...
// declares that a template takes a text buffer as input parameter. In the
// new version of Susan it should be written like this instead:
// ..., Text &var, ...
//
// - A line like this:
// ..., var /*BUFC*/, ...
// passes a text buffer to a template. In the new version of Susan it should
// be written like this instead:
// ..., &var, ...
//
// - Style guidelines:
//
// - Try (hard) to limit each row to 80 characters
//
// - Code for a template should be indented with 2 spaces
//
// - Exception to this rule is if you have only a single case, then that
// single case can be written using no indentation
//
// This single case can be seen as a clarification of the input to the
// template
//
// - Code after a case should be indented with 2 spaces if not written on the
// same line
