+# Demonstration of templates being re-written for a specific argument specification
+
+## Requirements
+
+* mustache
+* bison (to compile)
+* flex (to compile)
+
+## How to re-write
+
+```sh
+mustache demo.yml ../templates/<file>
+```
+
+To save the result to a file:
+
+```sh
+mustache demo.yml ../templates/<file> /path/to/output/file
+```
+
+## How to run
+
+Run `mustache` on all the templates in `../templates/`, and on _`main.cpp`_ (in this folder) to an empty output directory (`/path/to/output`).
+Then:
+
+```sh
+bison /path/to/output/*.yy
+flex /path/to/output/*.ll
+g++ /path/to/output/*.cpp /path/to/output*.cc -o demo
+/path/to/output/demo
+```
