SUMMARY = "VMcore extraction tool"
DESCRIPTION = "\
    This program is used to extract a subset of the memory available either \
    via /dev/mem or /proc/vmcore (for crashdumps). It is used to get memory \
    images without extra uneeded information (zero pages, userspace programs, \
    etc). \
