Comments
Comments in the style of C and C++ can be included in CPO files.
For example:
x = intVar(1..10); // This is single line comment (ends by new line).
y = x + /* This is another comment. */ + 5;
/*
* And this is multi-line comment.
*/
White space
ASCII white space (space, tab) and end of line are ignored during the parsing. An exception is identifiers enclosed in quotes.
