script_code is any code in the chosen scripting language. Parsing of the semantic patch does not check the validity of this code; any errors are first detected when the code is executed. Furthermore, @ should not be use in this code. Spatch scans the script code for the next @ and considers that to be the beginning of the next rule, even if @ occurs within e.g., a comment.

virtual keyword is used to declare virtual rules. Virtual rules may be subsequently used as a dependency for the rules in the SmPL file. Whether a virtual rule is defined or not is controlled by the -D option on the command line.
