This is a grenade timer for use with TFC.  It will allow you to time
the priming of your grenades.  To use it, put gt.wav in your tfc/sound
directory.  Then make the following changes to your config:

alias +gr1 "primeone; play gt.wav;"
alias -gr1 "throwgren; wait; throwgren;"
alias +gr2 "primetwo; play gt.wav;"
alias -gr2 "throwgren; wait; throwgren;"
bind <key> gr1
bind <key> gr2

Now just replace <key> in each of the bind commands above to the keys
you want to use for your grenades and you're ready to go.
