# This is a simple shell-script wrapper for the POSIX system command "wc" to add some functionality:
# Presumably the POSIX $PATH variable places us (default: /usr/local/bin) ahead of usual system commands.

# CONFIGURATION:
wc=/usr/bin/wc	# the real wc, which presumably we have taken-over-for by being earlier in search path

# COMMAND-LINE ARGUMENTS:
while [[ $# -ne 0 ]]
