## Additional helper functions
SHTPL declares somme utility functions to use in templates as a sub-commands,
generally it is a 1 argument function that can be piped:
### lowerCase
To transform a string in lowercase:
```
Original value: $value
Lowercase value: $(lowerCase $value)
Lowercase piped: $(echo $value | lowerCase)
```
### slug
To transform a string in a safe name, special characters are turned into "_":
```
Original value: $value
Slug value: $(slug $value)
Slug piped: $(echo $value | slug)
```
### user-input
Asks the user to enter text input at template execution and put it in place,
multiline text is supported because you'd have to type (ctrl-D) to validate input:
```
You entered: $(user-input Enter a value)
and the 2nd time this: $(user-input 'Question with simple quote')
the last one is turned to lowercase: $(user-input To be turned in lowercase | lowerCase)
```
