Usage: $0 [OPTIONS]
Options are:
-v, --verbose          display verbose messages. Also enables wget's continue
                      option.
--catchup_all          write all urls to the log file without downloading the
                      actual podcasts. This is useful if you want to subscribe
                      to some podcasts but don't want to download all the back
                      issues. You can edit the podcast.log file afterwards to
                      delete any url you still wish to download next time
                      bashpodder is run.
--first_only           grab only the first new enclosed file found in each feed.
                      The --catchup_all flag won't work with this option. If
                      you want to download the first file and also permanently
                      ignore the other files, run bashpodder with this option,
                      and then run it again with --catchup_all.
-bt --bittorrent       launch bittorrent for any .torrent files downloaded.
                      Bittorrent must be installed for this to work. The
                      the script and bittorrent process will continue running
                      in the foreground indefinitely. You can use ctr-c to
                      kill it when you want to stop participating in the
                      torrent.
--sync_disks           run the "sync" command twice when finished. This helps
                      makes sure all data is written to disk. Recommended if
                      data is being written directly to a portable player or
                      other removable media.
-u, --url_list         ignore bp.conf, instead use url(s) provided on the
                      command line. The urls should point to rss feeds.
                      If used, this needs to be the last option on the
                      command line. This can be used to quickly download just
                      a favorite podcast, or to take a few new podcasts for a
                      trial spin.
-h, --help             display this help message
