[emf-dev] JMerge examples?

[<andrew@xxxxxxxxxx>]

Hi, I'm looking for examples or documentation for jmerge?

I've got jet working and want to do code merge on my generated code.
Using the JET tutorial I got the system working, but I can't understand
the JMerge control file I copied from org.eclipse.emf.codegen.

What do the following statements mean?

    <merge:dictionaryPattern
      name="generatedUnmodifiableMembers"
      select="Member/getComment"
      match="\s*@\s*(gen)erated\s*\n"/>

    <merge:dictionaryPattern
      name="generatedModifiableMembers"
      select="Member/getComment"
      match="\s*@\s*generated\s*(modifiable)\s*\n"/>

JMerger is getting called, but it isn't doing anything to merge the two
version of the code.

Thanks,
ANdrew
