How file names, directories and localnames are mangled and managed
started in February 2009. Remote commands on MS Windows hosts since
September 2011. Ad-hoc multi-hop methods (with a changed syntax)
re-enabled in November 2011. In November 2012, added Juergen
-Hoetzel's @file{tramp-adb.el}.
+Hoetzel's @file{tramp-adb.el}. Archive file names are supported since
+December 2017.
XEmacs support was stopped in January 2016. Since March 2017,
@value{tramp} syntax mandates a method.
This user option is a list of external methods for GVFS@. By default,
this list includes @option{afp}, @option{dav}, @option{davs},
@option{gdrive}, @option{obex}, @option{sftp} and @option{synce}.
-Other methods to include are: @option{ftp} and @option{smb}.
+Other methods to include are @option{ftp}, @option{http},
+@option{https} and @option{smb}. These methods are not intended to be
+used directly as GVFS based method. Instead, they are added here for

+
+@value{tramp} offers also transparent access to files inside file
+archives. This is possible only on machines which have installed the
+virtual file system for the Gnome Desktop (GVFS), @ref{GVFS based
+methods}. Internally, file archives are mounted via the GVFS
+@option{archive} method.
+
+A file archive is a regular file of kind @file{/path/to/dir/file.EXT}.
+The extension @samp{.EXT} identifies the type of the file archive. A
+file inside a file archive, called archive file name, has the name
+@file{/path/to/dir/file.EXT/dir/file}.
+
+Most of the @ref{Magic File Names, , magic file name operations,
+elisp}, are implemented for archive file names, exceptions are all
+operations which write into a file archive, and process related
+operations. Therefore, functions like
+
+@lisp
+(copy-file "/path/to/dir/file.tar/dir/file" "/somewhere/else")
+@end lisp
+
+@noindent
+work out of the box. This is also true for file name completion, and
+for libraries like @code{dired} or @code{ediff}, which accept archive
+file names as well.
+
+@vindex tramp-archive-suffixes
+File archives are identified by the file name extension @samp{.EXT}.
+Since GVFS uses internally the library @code{libarchive(3)}, all
+suffixes, which are accepted by this library, work also for archive
+file names. Accepted suffixes are listed in the constant
+@code{tramp-archive-suffixes}. They are

+@samp{.lzma}, @samp{.lzo}, @samp{.uu}, @samp{.xz} and @samp{.Z}. A
+valid archive file name would be
+@file{/path/to/dir/file.tar.gz/dir/file}. Even several suffixes in a
+row are possible, like @file{/path/to/dir/file.tar.gz.uu/dir/file}.
+
+@vindex tramp-archive-all-gvfs-methods
+An archive file name could be a remote file name, as in
+@file{/ftp:anonymous@@ftp.gnu.org:/gnu/tramp/tramp-2.3.2.tar.gz/INSTALL}.
+Since all file operations are mapped internally to GVFS operations,
+remote file names supported by @code{tramp-gvfs} perform better,
+because no local copy of the file archive must be downloaded first.
+For example, @samp{/sftp:user@@host:...} performs better than the
+similar @samp{/scp:user@@host:...}. See the constant
+@code{tramp-archive-all-gvfs-methods} for a complete list of
+@code{tramp-gvfs} supported method names.
+
+If @code{url-handler-mode} is enabled, archives could be visited via
+URLs, like @file{https://ftp.gnu.org/gnu/tramp/tramp-2.3.2.tar.gz/INSTALL}.
+This allows complex file operations like
+
+@lisp
+@group
+(ediff-directories
+ "https://ftp.gnu.org/gnu/tramp/tramp-2.3.1.tar.gz/tramp-2.3.1"
+ "https://ftp.gnu.org/gnu/tramp/tramp-2.3.2.tar.gz/tramp-2.3.2" "")
+@end group
+@end lisp
+
+It is even possible to access file archives in file archives, as
+
+@lisp
+@group
+(find-file
