# Samhain stealth mode options
#
# If you would like to enable stealth mode, please set and uncomment the
# following options or pass them as enviroment variables when emerging
# the package (like INSTALL_NAME="asd" emerge samhain).
# If you set the variables here, don't forget to redigest the ebuild by
# issuing 'ebuild samhain-<thisversion>.ebuild digest', also remember that with
# your next emerge sync, the changes to the ebuild will be lost!
#
# Read the Samhain manual for additional information.
#
# STEALTH should be set to either 'full' or 'micro' (mandatory)
#STEALTH=""
#
# XOR_VALUE should be a whole number from 128 to 255 (mandatory)
#XOR_VALUE=""
#
# INSTALL_NAME can be set to change the name of the Samhain binaries
# to the name you specify (optional)
#INSTALL_NAME=""
