In the limits(1) man page:
Within a shell script, limits will normally be used with eval
within backticks as follows:
eval `limits -e -C daemon`
which causes the output of limits to be evaluated and set by the
current shell.
Ignore the part about "Within a shell script" -- it applies to an
interactive shell as well.
