# time - use to determine the amount of time used by a program. The
# resolution is .02 seconds. Time only determines the real time consumed;
# this will generally be more than the cpu time used by a program.
# The use of $* is not exactly elegant, as variable replacement is performed
# after alias replacement thus precluding any alias substitution. Also,
# the $* must be a simple command (no pipes...), or a script containing
# more complex commands.
#
# Time is presented as is; no warrantee is either expressed or implied
# as to it's suitability to any purpose whatsoever. You assume all the
# risk for all damage, even if caused by a defect in the software,
# no matter how awful.
