Hi Stephen,
A package can overwrite a method in a system class or in a class from other
package it depends on. For example if you package name is ‘Siren’ you have
to put the new method in a message category starting with ‘*siren’, such as
‘*siren-printing’, etc (or ‘*Siren-printing’, case doesn’t matter).
