Performance Co-Pilot archive writing library and headers

 The libpcp-archive-dev package contains the library and header files
 needed to build an application that creates a Performance Co-Pilot
 (PCP) archive suitable for use with the PCP tools.
 .
 The Performance Co-Pilot provides a unifying abstraction for
 all of the interesting performance data in a system, and allows
 client applications to easily retrieve and process any subset of
 that data.
