  <description>
  This bundle provides SLF4j implementation and configuration required to run m2e embedded Maven runtime
  in external JVM. This bundle is NOT a general purpose slf4j-simple OSGi bundle, it does NOT export
  any packages and it CANNOT be used as an OSGI SLF4J implementation.

  This is suboptimal and a better solution would be to either include slf4j-simple as a resource in
  org.eclipse.m2e.maven.runtime or use SLF4J implementation of the running m2e instance. I could not
  find an easy way to implement either of the better solutions, so this one will have to do for now. 

  This bundle is referenced as Require-Bundle by org.eclipse.m2e.maven.runtime to force installation
  of this bundle whenever m2e embedded maven runtime is installed. Because no packages are exported,
  this does not pollute OSGi classpath. Provide-Capability/Require-Capability would be cleaner, but
  I don't know if these are supported bu P2.
