# starts bittorrent in a detached screen session from your browser 
# optionally on another host. if it worked (or thinks it did) you
# will only see the something.torrent file download whereever your
# browser puts it, if not, youll get an xmessage telling you what
# (might have) went wrong. all the variables are in front, either
# change them or make a conf file with them.

# this ones cleaned up, it was 4 lines. 
# limitations: 
# 	only tested from firefox
#	populates ~. if anyone cares, ill add a DL directory option
# todo:
#	download directory
#	http://forums.macosxhints.com/archive/index.php/t-42616.html
#	osascript -e 'tell app "Finder" to display dialog "Hey!"'

# disclaimer: brahm cohen, the maker of bittorrent doesnt even know 
# this exists, let alone has anything to do with it. in fact hed 
# probably laugh at it, and you if you bug him about it. (and me
# for writing it) complain to pixel (the mail server is gimp.org) 
# see http://pixelfairy.org/ for other silly screen and ssh scripts. 

# furthur disclaimer, as you can see, the comments are longer than the 
# code. sucks to code these days...
