# failaction specifies what to do when an error occurs. You can specify
# ask, remove, maintain or move. ask makes axelq ask each time what to do.
# remove will auto-remove the download and start the next. maintain will
# retry and move will move the download to the end of the queue. This
# setting is case-sensitive.
#
# NOTE: best is to keep this to its default. maintain will cause axelq to
# retry until it dies. This is not good, since it will cause unnecessary
# bandwidth consumption for both you and the server. This is rude.
# move will act like maintain, if there is only one file in the queue.
