A not normally very easy to examine, but useful duplicate & paste structure is chosen through this manual. In this particular format all instructions are represented in code boxes, in which the comments are specified in blue shade. To avoid wasting House, normally several commands are concatenated on 1 line and divided using a semicolon ';'.
