to reasonably expect the network error to be fixed before the
retry.
+`--waitretry=SECONDS'
+ If you don't want Wget to wait between *every* retrieval, but only
+ between retries of failed downloads, you can use this option.
+ Wget will use "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 SECONDS you
+ specify. Therefore, a value of 10 will actually make Wget wait up
+ to (1 + 2 + ... + 10) = 55 seconds per file.
+
+ Note that this option is turned on by default in the global
+ `wgetrc' file.
+
`-Y on/off'
`--proxy=on/off'
Turn proxy support on or off. The proxy is on by default if the
on a proxy server. Wget will encode them using the `basic'
authentication scheme.
+`--referer=URL'
+ Include `Referer: URL' header in HTTP request. Useful for
+ retrieving documents with server-side processing that assume they
+ are always being retrieved by interactive web browsers and only
+ come out properly when Referer is set to one of the pages that
+ point to them.
+
`-s'
`--save-headers'
Save the headers sent by the HTTP server to the file, preceding the
header, and compare the sizes; if they are not the same, the remote
file will be downloaded no matter what the time-stamp says.

-FTP Time-Stamping Internals
-===========================
-
- In theory, FTP time-stamping works much the same as HTTP, only FTP
-has no headers--time-stamps must be received from the directory
-listings.
-
- For each directory files must be retrieved from, Wget will use the
-`LIST' command to get the listing. It will try to analyze the listing,
-assuming that it is a Unix `ls -l' listing, and extract the
-time-stamps. The rest is exactly the same as for HTTP.
-
- Assumption that every directory listing is a Unix-style listing may
-sound extremely constraining, but in practice it is not, as many
-non-Unix FTP servers use the Unixoid listing format because most (all?)
-of the clients understand it. Bear in mind that RFC959 defines no
-standard way to get a file list, let alone the time-stamps. We can
-only hope that a future standard will define this.
-
- Another non-standard solution includes the use of `MDTM' command
-that is supported by some FTP servers (including the popular
-`wu-ftpd'), which returns the exact time of the specified file. Wget
-may support this command in the future.
