SUMMARY = "Report application memory usage in a meaningful way"
DESCRIPTION = "smem is a tool that can give numerous reports on memory usage on Linux \
systems. Unlike existing tools, smem can report proportional set size (PSS), \
which is a more meaningful representation of the amount of memory used by \
libraries and applications in a virtual memory system."
