@section HTTP Options
@table @samp
+@cindex .html extension
+@item -E
+@itemx --html-extension
+If a file of type @samp{text/html} is downloaded and the URL does not
+end with the regexp "\.[Hh][Tt][Mm][Ll]?", this option will cause the
+suffix @samp{.html} to be appended to the local filename. This is
+useful, for instance, when you're mirroring a remote site that uses
+@samp{.asp} pages, but you want the mirrored pages to be viewable on
+your stock Apache server. Another good use for this is when you're
+downloading the output of CGIs. A URL like
+@samp{http://site.com/article.cgi?25} will be saved as
+@file{article.cgi?25.html}.
+
+Note that filenames changed in this way will be re-downloaded every time
+you re-mirror a site, because wget can't tell that the local
+@file{@var{X}.html} file corresponds to remote URL @samp{@var{X}} (since
+it doesn't yet know that the URL produces output of type
+@samp{text/html}. To prevent this re-downloading, you must use
+@samp{-k} and @samp{-K} so that the original version of the file will be
+saved as @file{@var{X}.orig} (@xref{Recursive Retrieval Options}).

@section FTP Options
@table @samp
-@cindex retrieve symbolic links
+@cindex symbolic links, retrieving
@item --retr-symlinks
-Retrieve symbolic links on @sc{ftp} sites as if they were plain files,
-i.e. don't just create links locally.
+Usually, when retrieving @sc{ftp} directories recursively and a symbolic
+link is encountered, the linked-to file is not downloaded. Instead, a
+matching symbolic link is created on the local filesystem. The
+pointed-to file will not be downloaded unless this recursive retrieval
+would have encountered it separately and downloaded it anyway.
+
+When @samp{--retr-symlinks} is specified, however, symbolic links are
+traversed and the pointed-to files are retrieved. At this time, this
+option does not cause wget to traverse symlinks to directories and
+recurse through them, but in the future it should be enhanced to do
+this.
+
+Note that when retrieving a file (not a directory) because it was
+specified on the commandline, rather than because it was recursed to,
+this option has no effect. Symbolic links are always traversed in this
+case.

@section Wgetrc Commands
@cindex wgetrc commands
-The complete set of commands is listed below, the letter after @samp{=}
-denoting the value the command takes. It is @samp{on/off} for @samp{on}
-or @samp{off} (which can also be @samp{1} or @samp{0}), @var{string} for
-any non-empty string or @var{n} for a positive integer. For example,
-you may specify @samp{use_proxy = off} to disable use of proxy servers
-by default. You may use @samp{inf} for infinite values, where
-appropriate.
+The complete set of commands is listed below. Legal values are listed
+after the @samp{=}. Simple Boolean values can be set or unset using
+@samp{on} and @samp{off} or @samp{1} and @samp{0}. A fancier kind of
+Boolean allowed in some cases is the "lockable" Boolean, which may be
+set to @samp{on}, @samp{off}, @samp{always}, or @samp{never}. If an
+option is set to @samp{always} or @samp{never}, that value will be
+locked in for the duration of the wget invocation -- commandline options
+will not override.
+
+Some commands take pseudo-arbitrary values. @var{string} values can be
+any non-empty string. @var{n} can be any positive integer, or
+@samp{inf} for infinity, where appropriate.
-Most of the commands have their equivalent command-line option
-(@xref{Invoking}), except some more obscure or rarely used ones.
+Most of these commands have commandline equivalents (@xref{Invoking}),
+though some of the more obscure or rarely used ones do not.
@table @asis
@item accept/reject = @var{string}
@item header = @var{string}
Define an additional header, like @samp{--header}.
+@item html_extension = on/off
+Add a @samp{.html} extension to @samp{text/html} files without it, like
+@samp{-E}.
+
@item http_passwd = @var{string}
Set @sc{http} password.
Download all ancillary documents necessary for a single HTML page to
display properly -- the same as @samp{-p}.
-@item passive_ftp = on/off
-Set passive @sc{ftp} -- the same as @samp{--passive-ftp}.
+@item passive_ftp = on/off/always/never
+Set passive @sc{ftp} -- the same as @samp{--passive-ftp}. Some scripts
+and @samp{.pm} (Perl module) files download files using @samp{wget
+--passive-ftp}. If your firewall does not allow this, you can set
+@samp{passive_ftp = never} to override the commandline.
@item passwd = @var{string}
Set your @sc{ftp} password to @var{password}. Without this setting, the
password defaults to @samp{username@@hostname.domainname}.
@item proxy_user = @var{string}
-Set proxy authentication user name to @var{string}, like
-@samp{--proxy-user}.
+Set proxy authentication user name to @var{string}, like @samp{--proxy-user}.
@item proxy_passwd = @var{string}
-Set proxy authentication password to @var{string}, like
-@samp{--proxy-passwd}.
+Set proxy authentication password to @var{string}, like @samp{--proxy-passwd}.
+
+@item referer = @var{string}
+Set HTTP @samp{Referer:} header just like @samp{--referer}. (Note it
+was the folks who wrote the @sc{http} spec who got the spelling of
+"referrer" wrong.)
@item quiet = on/off
Quiet mode -- the same as @samp{-q}.
