    The Packcore utility helps pack a core file with its context, including the executable,
application, and shared system libraries from the current environment. This information can
be unpacked for later debugging on a different system. Packcore extracts the name of the binary
that generated the core from the core file, then executes `ldd` (List Dynamic Dependencies)
to create a single tar archive containing the core file information.
