## Functions
## Named Functions
These are used by some of the other functions to provide flexibility
| Function | Description |
|-------------|---------------------------------------------------------------------------------------------------------------------------------------|
| retval | Returns the first argument or a '.' if no arguments are specified |
| retlog | Returns the first argument or /var/log/nginx/access.log if no arguments are specified |
