# A script to summarize system information in a nice way.
# Goals: work well on Linux; create a compact diff-able report that is
# easy to paste into a wiki or email, and easy to scan and compare too.
#
# Usage: $ wget -O-  |bash
# Options are set through the ASPERSA_SKIP environment variable.  Set this
# variable to a comma-separated list of things you want to omit.
# Options:
#  MOUNT:   Don't print out mounted filesystems and disk fullness.
#  NETWORK: Don't print out information on network controllers & config.
#  PROCESS: Don't print out top processes and vmstat information.

# so on, until it finds a number that's large enough.  The pattern is slightly
