/*
$droploc
Tells location of the dropped flag.
Note: This will tell only if you have dropped the flag (CTF/TF). 

$droptime
Tells how many seconds gone of dropped flag.

$ledpoint
This reports the type of the pointed object as a LED according to the
following rules:
If teammate then green.
If enemy then red.
If powerup then yellow.
if item then blue. 

$ledstatus
This checks your current status (health, armor and best weapon) and
reports a LED according to the following rules:
if all of the above is ok then green.
if there is one thing low then yellow.
if there are two or over things low then red.

$matchname
you can use to get the name of the match
manually (echo $matchname).
Example: a matchname might be
"[clan]quaker - [4on4_myclan_vs_someclan] - [dm3]" or whatever.

$matchstatus
("disconnected", "standby" or "normal"). This can be
used for detecting prewar/prematch on ktpro/oztf servers.

$matchtype
duel,2on2,4on4,ffa,etc...

$mp3info
Evaluates to "author - title".
Examples:
if you bind space "say listening to $mp3info"
then hitting space will say something like
"listening to disturbed - rise".
bind x "if disturbed isin $mp3info then say dde music is cool"

$need
What you need.
Note: you have to set this with tp_need* variables.

$point
Name of object you are looking at.

$pointatloc
Name of object and location of object you are looking at.

$pointloc
Location of object you are looking at.

$triggermatch
$triggermatch is the last chat message that exec'd a msg_trigger.
