What is this package?

The library files in here are pulled in from Artifactory in the build script for this module.  They
are loaded directly from the MPLABComm JAR file that is distributed with the MPLABComm module.

How do I update the files in this package?

Delete the extlibs directory and resolved-ivy.xml and rebuild in order to get the latest continuous integration 
version of each library.

Should these files be in version control?

No.  They're part of artifactory.  The revisions of the files in this package that make it into a release should 
be promoted to release.  The files that are part of a release candidate should be promoted to milestone so that 
they don't get purged by mistake.
