Does a ChangeSetSlice record the preamble and postscript? Do these get run automaticaly when a ChangeSetSlice is loaded?<br>

No, that doesn't really fit with MC's versioning model.<br>

Does your closure bootstrap have preamble and postscript? What do they do?</blockquote><div><br></div><div>There are a few.
