feature request: unclude tag

[rukeba]

It would be great if mustache has support of include tag:

{{#include 'path-to-other-mustache-template-file.html'}}

+1. A use case would be for when you want a footer on all emails sent out. Personally I just started using mustache-sharp for email template generation, so this would make things easier in that scenario.
