 ### Variables
 - Variable names must only consist of these characters: `a-zA-Z0-9_`
 - A variable with name `varname` can be used like this: `#$(varname)`

 - Any variable that has is not defined has empty string as value

 - If a command-comment takes up a whole line, the whole line including the newline character is replaced.
