i am told that this file, btreannounce.py can edit mutliples torrents ( 100+) without change other than announce url ( sha1, etc).
i download python six days ago and understand basic stuff.
my problem; i dont understand how it running properly so i can edit announce url for all torrents.
i often get new errors such as
Traceback (most recent call last): --- File "C:\Python24\BitTornado-CVS\btreannounce.py", line 34, in -toplevel- exit(2) # common exit code for syntax error SystemExit: 2 ---
and other.
here is source of this file
