Guys, could you please tell a few words about how to use this in production code? I.e. where asking the users to install the EUSERHL.SIS is not an option. Mentioning using embedded SIS files and a link to a wiki page describing how to do it would be almost sufficient. Also an example PKG file line. I don't seem to find any information about the EUSERHL.SIS UID, which makes it impossible to create an embedded SIS. Then a few words about how (or if) getting EUSERHL.SIS is possible would also be nice. Otherwise the whole package is just unusable.
