usage() {
cat <<-'_usage_statement_'
The script is_spammer.bash requires either one or two arguments.
arg 1) May be one of:
a) A domain name
b) An IPv4 address
c) The name of a file with any mix of names
and addresses, one per line.
arg 2) May be one of:
a) A Blacklist server domain name
b) The name of a file with Blacklist server
domain names, one per line.
c) If not present, a default list of (free)
Blacklist servers is used.
d) If a filename of an empty, readable, file
is given,
Blacklist server lookup is disabled.
All script output is written to stdout.
Return codes: 0 -> All OK, 1 -> Script failure,
2 -> Something is Blacklisted.
Requires the external program 'dig' from the 'bind-9'
set of DNS programs.  See: http://www.isc.org
The domain name lookup depth limit defaults to 2 levels.
Set the environment variable SPAMMER_LIMIT to change.
SPAMMER_LIMIT=0 means 'unlimited'
Limit may also be set on the command-line.
If arg#1 is an integer, the limit is set to that value
and then the above argument rules are applied.
Setting the environment variable 'SPAMMER_DATA' to a filename
will cause the script to write a GraphViz graphic file.
For the development version;
Setting the environment variable 'SPAMMER_TRACE' to a filename
will cause the execution engine to log a function call trace.
