RE: Embedding - howto

The "jars@ folder is derived from the artifact type.  If no type is
specificed then "jar" is assumed as the type.  The artifact spec is
expanded as follows for versioned artifacts:

  [repository-cache]/[group]/[type]s/[name]-[version].[type]

For artifacts that do not declare a version its:

  [repository-cache]/[group]/[type]s/[name].[type]

Ok, I THINK I understand now, but perhaps you could confirm if my
assumption
is correct, since it is only a guess.

My guess is that using
"artifact:jar:avalon/merlin/avalon-merlin-impl#SNAPSHOT" is telling the
resolver to look in ${magic.home}/repository, in the directoy
"avalon/merlin". I guess that the folder "jars" is assumed, so the final
part of this "path" just tells what jar we want.

So, if this guess is correct, say I wanted to lookup the avalon
framework
component, would the "path" be written as:

artiface:jar:avalon/framework/avalon-framework-impl#SNAPSHOT?
