##################
Welcome to Temple!
Temple is designed to template text with simple string key/value pairs.
For example in this file we have three template variables defined:
- app
- flag
- key
We tell temple the path to our filename with the --file flag:
temple --file ./example.tpl
If you omit the --file flag, temple will read from stdin:
cat ./example.tpl | temple
To actually set the values of the template variables, we need to pass each each one as an argument like this:
temple --file ./example.tpl app=temple flag=--file key=value
Or using stdin
cat ./example.tpl | temple app=temple
Each key/value pair must be separated with an "=".

Templating tips and tricks
Temple also includes the sprig library (https://http://masterminds.github.io/sprig), which extends the standard go templating library significantly.
