## Brief docs

## 1) Place vtvauto.pl in $HOME/.irssi/scripts

## 2) Place vtvshows.txt in $HOME/.irssi/ where each shows is on their own line
## you can use regular expressions

## /script load vtvauto 
## to load the script

## /set dcc_autoget ON
## /set dcc_autoget_masks *!*botty@benzoate.mine.nu
## /set dcc_download_path ~/launchmanydir

## the dcc_download_path is the most important ingredient

## YOU NEED TO HAVE BitTorrent or BitTornado launchmany.py or launchmanycurses.py 
## watching that dcc_download_path

## /vtvreload to reload vtvshows.txt
## /vtvshows to display current list
## /vtvdebug to change debug level, 0 = no debug, 1 = general debug, 2 = verbose debug
## changelog:
## 20050916
## - added support for non "!trigger" triggers
## 20050913
## - fixed nick detection to use hostmask instead
## - detects now secondary announces too if you happened to be on netsplit 
##   when first one occured
## - added /vtvdebug 
## 20050910
