#
#   This program may be used to create a /etc/shorewall/capabilities file for
#   use in compiling Shorewall firewalls on another system.
#
#   On the target system (the system where the firewall program is to run):
#
#       [ IPTABLES=<iptables binary> ] [ MODULESDIR=<kernel modules directory> ] [ MODULE_SUFFIX="<module suffix list>" ] shorecap > capabilities
#
#    Now move the capabilities file to the compilation system. The file must
#    be placed in a directory on the CONFIG_PATH to be used when compiling firewalls
#    for the target system.
#
#    Default values for the two variables are:
#
#        IPTABLES - iptables
#        MODULESDIR - /lib/modules/$(uname -r)/kernel/net/ipv4/netfilter
#        MODULE_SUFFIX - "o gz xz ko o.gz o.xz ko.gz ko.xz"
#
#    Shorewall need not be installed on the target system to run shorecap. If the '-e' flag is
#    used during firewall compilation, then the generated firewall program will likewise not
#    require Shorewall to be installed.
