# /AUTOAWAY <n> - Mark user away after <n> seconds of inactivity
# /AWAY - play nice with autoaway
# New, brighter, whiter version of my autoaway script. Actually works :)

# A simple script. /autoaway <n> will mark you as away automatically if
# you have not typed any commands in <n> seconds. (<n>=0 disables the feature)
# It will also automatically unmark you away the next time you type a command.
# Note that using the /away command will disable the autoaway mechanism, as
# well as the autoreturn. (when you unmark yourself, the auutoaway wil
# restart again)
