Note that a combination with @samp{-k} is only permitted when
downloading a single document, as in that case it will just convert
all relative URIs to external ones; @samp{-k} makes no sense for

between retries of failed downloads, you can use this option. Wget will
use @dfn{linear backoff}, waiting 1 second after the first failure on a
given file, then waiting 2 seconds after the second failure on that
-file, up to the maximum number of @var{seconds} you specify. Therefore,
-a value of 10 will actually make Wget wait up to (1 + 2 + ... + 10) = 55
-seconds per file.

By default, Wget will assume a value of 10 seconds.
You can set the default encoding using the @code{remoteencoding}
command in @file{.wgetrc}. That setting may be overridden from the
command line.
