preview_template.py allows you to test a Django template located in the current working directory (first argument). The template is rendered with the given context (second argument, optional), and the result is immediately piped into the browser with the bcat utility.

Usage:

python preview_template.py [template name] [context]

Example:

python preview_template.py template.html "{'username': 'Његош'}"
