<#comment>
This demonstrates the FreeMarker language. The default theme is not very
colorful and displays many different token types in the same color, but keep in
mind that you can define your own theme (or extend an existing one).

Note that free marker actually defines 6 similar but different syntax modes:

- 3 tag syntax modes: Angle (<#if>), Bracket ([#if]), and Auto.
- 2 interpolation modes: Dollar (${...}) and Bracket ([=...])

In auto mode, the first tag determines the tag syntax. You can use the language
IDs "freemarker.tag-bracket.interpolation-dollar" etc. to force a specific mode.

The default FreeMarker mode is Angle/Dollar.
