Ned,

You need to use the PackagePanel FileIn button instead.  Load is meant for
bringing in new versions, not updating existing ones.  To address your
main point of confusion - the .st files are straight file outs, it's the
way they're filed in that's special.

Programmatically, I think you'd need to do something like

|current new|
current := ImagePackageLoad new package: (PackageInfo named:
'PackageName').
new := StreamPackageLoader new stream: myFileStream.
(new changesFromBase: current) fileIn.

Does that help?
