+Prints to stdout the built-in template. Useful if you want to
+customize the appearance of your document. E.g., if you want to modify
+the CSS used for HTML rendering:
+
+```
+$ crowbook --print-template html.css > my_style.css
+# edit my_style.css in your favourite editor
+$ crowbook my.book --set html.css my_style.css
+# or add "html.css: my_style.css" in my.book
+```

+
+```
+$ crowbook --print-template epub.template --set epub.version 2
+# Returns the template for Epub 2 (default one)
+$ crowbook --print-template epub.template --set epub.version 3
+# Returns the template for Epub 3
