to stderr, with configurable error log level threshold (-E option).
Created -e<filename> option to tee error messages to file and stderr.
Created -o<filename> option to send console output to file (like a pipe).
All options (except for -h) now support -x<value> and -x <value> syntax.
When no argument is passed with -h, it acts like -H (uses local hostname).
Removed -H option (redundant now).
