    Hmmn, how about:

    User Commands nice(1)

    NAME
    nice - invoke a command with an altered priority

    SYNOPSIS
    /usr/bin/nice [-increment | -n increment] [-s|-i|-e|-p] command [argu-
    ment...]

    DESCRIPTION
    The nice utility invokes command, requesting that it be run
    with a different priority. If -i is specified, the priority
    of (disk) I/O is modified. If -e is specified, ethernet (or
    other networking) priority is changed. If -p is specified, power
    usage priority is changed and if -s is specified, or none
    of -1, -e or -p is specified, then system scheduling priority
    is modified...
