- While in a `yacas` session, display an example:

`{{Example()}};`

- Quit from a `yacas` session:

`{{quit}}`

- Execute one or more `yacas` scripts (without terminal or prompts), then exit:

`yacas -p -c {{path/to/script1}} {{path/to/script2}}`

- Execute and print the result of one statement, then exit:

`echo "{{Echo( Deriv(x)Cos(1/x) );}}" | yacas -p -c /dev/stdin`
