In  the comments of SMSARInstaller I read that:

See ChangeSet>>fileOutAsZipNamed: for one way to make these files. Here 
is another way of creating a multi change set archive installable by 
SqueakMap:

"The following doit will create a .sar file with HVs preamble and 
postscript as
separate entries and the included changesets included as normal.
Given a preamble as described below this will autoinstall in SqueakMap."
(ChangeSorter changeSetNamed: 'HV')
	fileOutAsZipNamed: 'httpview-021023.sar'
	including: {
		ChangeSorter changeSetNamed: 'HVFixes'.
		ChangeSorter changeSetNamed: 'kom412'}


But I cannot find implementors of fileOutAsZipNamed:
Any idea where they went :)
