 @chapter An overview of @value{tramp}
 @cindex overview
 
-After the installation of @value{tramp} into your @value{emacsname}, you
-will be able to access files on remote hosts as though they were
-local.  Access to the remote file system for editing files, version
-control, and @code{dired} are transparently enabled.
-
-Your access to the remote host can be with the @command{rsh},
-@command{rlogin}, @command{telnet} programs or with any similar
-connection method.  This connection must pass @acronym{ASCII}
-successfully to be usable but need not be 8-bit clean.
-
-The package provides support for @command{ssh} connections out of the
-box, one of the more common uses of the package.  This allows
-relatively secure access to hosts, especially if @command{ftp}
-access is disabled.
-
-Under Windows, @value{tramp} is integrated with the PuTTY package,
-using the @command{plink} program.
-
-The majority of activity carried out by @value{tramp} requires only that
-the remote login is possible and is carried out at the terminal.  In
-order to access remote files @value{tramp} needs to transfer their content
-to the local host temporarily.
-
-@value{tramp} can transfer files between the hosts in a variety of ways.
-The details are easy to select, depending on your needs and the
-hosts in question.
-
-The fastest transfer methods for large files rely on a remote file
-transfer package such as @command{rcp}, @command{scp}, @command{rsync}
-or (under Windows) @command{pscp}.
-
-If the remote copy methods are not suitable for you, @value{tramp} also
-supports the use of encoded transfers directly through the shell.
-This requires that the @command{mimencode} or @command{uuencode} tools
-are available on the remote host.  These methods are generally
-faster for small files.
-
-@value{tramp} is still under active development and any problems you encounter,
-trivial or major, should be reported to the @value{tramp} developers.
-@xref{Bug Reports}.
+@value{tramp} is for transparently accessing remote files from within
+@value{emacsname}.  @value{tramp} enables an easy, convenient, and
+consistent interface to remote files as if they are local files.
+@value{tramp}'s transparency extends to editing, version control, and
+@code{dired}.
+
+@value{tramp} can access remote hosts using any number of access
+methods, such as @command{rsh}, @command{rlogin}, @command{telnet},
+and related programs.  If these programs can successfully pass
+@acronym{ASCII]} characters, @value{tramp} can use them.
+@value{tramp} does not require or mandate 8-bit clean connections.
+
+@value{tramp}'s most common access method is through @command{ssh}, a
+more secure alternative to @command{ftp} and other older access
+methods.
+
+@value{tramp} on Windows operating systems is integrated with the
+PuTTY package, and uses the @command{plink} program.
+
+@value{tramp} mostly operates transparently in the background using
+the connection programs.  As long as these programs enable remote login
+and can use the terminal, @value{tramp} can adapt them for seamless
+and transparent access.
+
+@value{tramp} temporarily transfers a remote file's contents to the
+local host editing and related operations.  @value{tramp} can also
+transfer files between hosts using standard Emacs interfaces, a
+benefit of direct integration of @value{tramp} in @value{emacsname}.
+
+@value{tramp} can transfer files using any number of available host
+programs for remote files, such as @command{rcp}, @command{scp},
+@command{rsync} or (under Windows) @command{pscp}.  @value{tramp}
+provides easy ways to specify these programs and customize them to
+specific files, hosts, or access methods.
+
+For faster small-size file transfers, @value{tramp} supports encoded
+transfers directly through the shell using @command{mimencode} or
+@command{uuencode} provided such tools are available on the remote
+host.

+@subsubheading @value{tramp} behind the scenes
 @cindex behind the scenes
 @cindex details of operation
 @cindex how it works
 
-This section tries to explain what goes on behind the scenes when you
-access a remote file through @value{tramp}.
+Accessing a remote file through @value{tramp} entails a series of
+actions, many of which are transparent to the user.  Yet some actions
+may require user response (such as entering passwords or completing
+file names).  One typical scenario, opening a file on a remote host, is
+presented here to illustrate the steps involved:
 
-Suppose you type @kbd{C-x C-f} and enter part of an @value{tramp} file name,
-then hit @kbd{@key{TAB}} for completion.  Suppose further that this is
-the first time that @value{tramp} is invoked for the host in question.  Here's
-what happens:
+@kbd{C-x C-f} to initiate find-file, enter part of the @value{tramp}
+file name, then hit @kbd{@key{TAB}} for completion.  If this is the
+first time connection to that host, here's what happens:
 
 @itemize
 @item
-@value{tramp} discovers that it needs a connection to the host.  So it
-invokes @samp{telnet @var{host}} or @samp{rsh @var{host} -l
-@var{user}} or a similar tool to connect to the remote host.
-Communication with this process happens through an
-@value{emacsname} buffer, that is, the output from the remote end
-goes into a buffer.
+@value{tramp} invokes @samp{telnet @var{host}} or @samp{rsh @var{host}
+-l @var{user}} and establishes an external process to connect to the
+remote host.  @value{tramp} communicates with the process through an
+@value{emacsname} buffer, which also shows output from the remote
+host.
 
 @item
-The remote host may prompt for a login name (for @command{telnet}).
-The login name is given in the file name, so @value{tramp} sends the
-login name and a newline.
+The remote host may prompt for a login name (for @command{telnet}, for
+example) in the buffer.  If on the other hand, the login name was
+included in the file name portion, @value{tramp} sends the login name
+followed by a newline.
 
 @item
-The remote host may prompt for a password or pass phrase (for
-@command{rsh} or for @command{telnet} after sending the login name).
-@value{tramp} displays the prompt in the minibuffer, asking you for the
-password or pass phrase.
-
-You enter the password or pass phrase.  @value{tramp} sends it to the remote
-host, followed by a newline.
+The remote host may then prompt for a password or pass phrase (for
+@command{rsh} or for @command{telnet}).  @value{tramp} displays the
+password prompt in the minibuffer.  @value{tramp} then sends whatever
+is entered to the remote host, followed by a newline.
 
 @item
-@value{tramp} now waits for the shell prompt or for a message that the login
-failed.
+@value{tramp} now waits for either the shell prompt or a failed login
+message.
 
-If @value{tramp} sees neither of them after a certain period of time
-(a minute, say), then it issues an error message saying that it
-couldn't find the remote shell prompt and shows you what the remote
-host has sent.
+If @value{tramp} does not receive any messages within a timeout period
+(a minute, for example), then @value{tramp} responds with an error
+message about not finding the remote shell prompt.  If any messages
+from the remote host, @value{tramp} displays them in the buffer.
 
-If @value{tramp} sees a @samp{login failed} message, it tells you so,
-aborts the login attempt and allows you to try again.
+For any @samp{login failed} message from the remote host,
+@value{tramp} aborts the login attempt, and repeats the login steps
+again.
 
 @item
-Suppose that the login was successful and @value{tramp} sees the shell prompt
-from the remote host.  Now @value{tramp} invokes @command{/bin/sh} because
-Bourne shells and C shells have different command
-syntaxes.@footnote{Invoking @command{/bin/sh} will fail if your login
-shell doesn't recognize @samp{exec /bin/sh} as a valid command.
-Maybe you use the Scheme shell @command{scsh}@dots{}}
+Upon successful login and @value{tramp} recognizes the shell prompt
+from the remote host, @value{tramp} prepares the shell environment by
+turning off echoing, setting shell prompt, and other housekeeping
+chores.
 
-After the Bourne shell has come up, @value{tramp} sends a few commands to
-ensure a good working environment.  It turns off echoing, it sets the
-shell prompt, and a few other things.
+@strong{Note} that for the remote shell, @value{tramp} invokes
+@command{/bin/sh}.  The remote host must recognize @samp{exec /bin/sh}
+and execute the appropriate shell.  This shell must support Bourne
+shell syntax.
 
 @item
-Now the remote shell is up and it good working order.  Remember, what
-was supposed to happen is that @value{tramp} tries to find out what files exist
-on the remote host so that it can do file name completion.
-
-So, @value{tramp} basically issues @command{cd} and @command{ls} commands and
-also sometimes @command{echo} with globbing.  Another command that is
-often used is @command{test} to find out whether a file is writable or a
-directory or the like.  The output of each command is parsed for the
-necessary operation.
+@value{tramp} executes @command{cd} and @command{ls} commands to find
+which files exist on the remote host.  @value{tramp} sometimes uses
+@command{echo} with globbing.  @value{tramp} checks if a file or
+directory is writable with @command{test}.  After each command,
+@value{tramp} parses the output from the remote host for completing
+the next operation.
 
 @item
-Suppose you are finished with file name completion, have entered @kbd{C-x
-C-f}, a full file name and hit @kbd{@key{RET}}.  Now comes the time to
-transfer the file contents from the remote host to the local host so
-that you can edit them.
-
-See above for an explanation of how @value{tramp} transfers the file contents.
+After remote file name completion, @value{tramp} transfers the file
+contents from the remote host.
 
-For inline transfers, @value{tramp} issues a command like @samp{mimencode -b
-/path/to/remote/file}, waits until the output has accumulated in the
-buffer that's used for communication, then decodes that output to
-produce the file contents.
+For inline transfers, @value{tramp} sends a command, such as
+@samp{mimencode -b /path/to/remote/file}, waits until the output has
+accumulated in the buffer, decodes that output to produce the file's
+contents.
 
-For external transfers, @value{tramp} issues a command like the
-following:
+For external transfers, @value{tramp} sends a command as follows:
 @example
 rcp user@@host:/path/to/remote/file /tmp/tramp.4711
 @end example
-It then reads the local temporary file @file{/tmp/tramp.4711} into a
-buffer and deletes the temporary file.
+@value{tramp} reads the local temporary file @file{/tmp/tramp.4711}
+into a buffer, and then deletes the temporary file.
 
 @item
-You now edit the buffer contents, blithely unaware of what has happened
-behind the scenes.  (Unless you have read this section, that is.)  When
-you are finished, you type @kbd{C-x C-s} to save the buffer.
+Edit, modify, change the buffer contents as normal, and then save the
+buffer wth @kbd{C-x C-s}.
 
 @item
-Again, @value{tramp} transfers the file contents to the remote host
-either inline or external.  This is the reverse of what happens when
-reading the file.
+@value{tramp} transfers the buffer contents to the remote host in
+a reverse of the process using the appropriate inline or external

-far, it is tested against MS Windows NT, MS Windows 2000, MS Windows
-XP, MS Windows Vista, and MS Windows 7.
-
-The first directory in the localname must be a share name on the remote
-host.  Remember that the @code{$} character, in which default shares
-usually end, must be written @code{$$} due to environment variable
-substitution in file names.  If no share name is given (i.e., remote
-directory @code{/}), all available shares are listed.
-
-Since authorization is done on share level, you will always be
-prompted for a password if you access another share on the same host.
-This can be suppressed by @ref{Password handling}.
-
-For authorization, MS Windows uses both a user name and a domain name.
-Because of this, the @value{tramp} syntax has been extended: you can
-specify a user name which looks like @code{user%domain} (the real user
-name, then a percent sign, then the domain name).  So, to connect to

-@code{BIZARRE}, and edit @file{.emacs} in the home directory (share
-@code{daniel$}) I would specify the file name @file{@trampfn{smb,
-daniel%BIZARRE, melancholia, /daniel$$/.emacs}}.
-
-Depending on the Windows domain configuration, a Windows user might be
-considered as domain user per default.  In order to connect as local
-user, the WINS name of that host must be given as domain name.
-Usually, it is the host name in capital letters.  In the example
-above, the local user @code{daniel} would be specified as
-@file{@trampfn{smb, daniel%MELANCHOLIA, melancholia, /daniel$$/.emacs}}.
-
-The domain name as well as the user name are optional.  If no user
-name is specified at all, the anonymous user (without password

+This is another non-native @value{tramp} method.  @command{smbclient}

+works with MS Windows NT, MS Windows 2000, MS Windows XP, MS Windows
+Vista, and MS Windows 7.
+
+Using @command{smbclient} requires a few tweaks when working with
+@value{tramp}:
+
+The first directory in the localname must be a share name on the
+remote host.
+
+Since smb shares end in the @code{$} character, @value{tramp} must use
+@code{$$} when specifying those shares to avoid environment variable
+substitutions.
+
+When @value{tramp} is not specific about the share name or uses the
+generic remote directory @code{/}, @command{smbclient} returns all
+available shares.
+
+Since SMB authentication is based on each SMB share, @value{tramp}
+prompts for a password even when accessing a different share on the
+same SMB host.  This prompting can be suppressed by @ref{Password
+handling}.
+
+To accommodate user name/domain name syntax required by MS Windows
+authorization, @value{tramp} provides for an extended syntax in
+@code{user%domain} format (where user is username, @code{%} is the
+percent symbol, and domain is the windows domain name).  An example:
+
+@example
+@trampfn{smb, daniel%BIZARRE, melancholia, /daniel$$/.emacs}
+@end example
+
+where user @code{daniel} connects as a domain user to the SMB host
+@code{melancholia} in the windows domain @code{BIZARRE} to edit
+@file{.emacs} located in the home directory (share @code{daniel$}).
+
+Alternatively, for local WINS users (as opposed to domain users),
+substitute the domain name with the name of the local host in
+UPPERCASE as shown here:
+
+@example
+@trampfn{smb, daniel%MELANCHOLIA, melancholia, /daniel$$/.emacs}
+@end example
+
+where user @code{daniel} connects as local user to the SMB host
+@code{melancholia} in the local domain @code{MELANCHOLIA} to edit
+@file{.emacs} located in the home directory (share @code{daniel$}).
+
+The domain name and user name are optional for @command{smbclient}
+authentication.  When user name is not specified, @command{smbclient}
+uses the anonymous user (without prompting for password).  This
+behavior is unlike other @value{tramp} methods, where local user name
+is substituted.
+
+@option{smb} method is unavailable if @value{emacsname} is run under a
+local user authentication context in MS Windows.  However such users
+can still access remote files using UNC file names instead of @value{tramp}:
+
+@example
+//melancholia/daniel$$/.emacs
+@end example
+
+UNC file name specification does not allow to specify a different user
+name for authentication like the @command{smbclient} can.

+@value{tramp} provides maximum number of choices for maximum

-@subsection Which method is the right one for me?
-@cindex choosing the right method
+Start by using an inline method.
 
-Given all of the above, you are probably thinking that this is all fine
-and good, but it's not helping you to choose a method!  Right you are.
-As a developer, we don't want to boss our users around but give them
-maximum freedom instead.  However, the reality is that some users would
-like to have some guidance, so here I'll try to give you this guidance
-without bossing you around.  You tell me whether it works @dots{}
-
-My suggestion is to use an inline method.  For large files, external
-methods might be more efficient, but I guess that most people will
-want to edit mostly small files.  And if you access large text files,
-compression (driven by @var{tramp-inline-compress-start-size}) shall
-still result in good performance.
-
-I guess that these days, most people can access a remote host by
-using @command{ssh}.  So I suggest that you use the @option{ssh}
-method.  So, type @kbd{C-x C-f @trampfn{ssh, root, otherhost,
-/etc/motd} @key{RET}} to edit the @file{/etc/motd} file on the other
-host.
+External methods might be more efficient for large files, but most
+@value{tramp} users edit small files more often than large files.
 
-If you can't use @option{ssh} to log in to the remote host, then
-select a method that uses a program that works.  For instance, Windows
-users might like the @option{plink} method which uses the PuTTY
-implementation of @command{ssh}.  Or you use Kerberos and thus like
-@option{krlogin}.
+Enable compression, @var{tramp-inline-compress-start-size}, for a
+performance boost for large files.
 
-For the special case of editing files on the local host as another
-user, see the @option{su} or @option{sudo} methods.  They offer
-shortened syntax for the @samp{root} account, like
-@file{@trampfn{su, , , /etc/motd}}.
+Since @command{ssh} has become the most common method of remote host
+access and it has the most reasonable security protocols, use
+@option{ssh} method.  Typical @option{ssh} usage to edit the
+@file{/etc/motd} file on the otherhost:
 
-People who edit large files may want to consider @option{scp} instead
-of @option{ssh}, or @option{pscp} instead of @option{plink}.  These
-external methods are faster than inline methods for large files.
-Note, however, that external methods suffer from some limitations.
-Please try first whether you really get a noticeable speed advantage
-from using an external method!  Maybe even for large files, inline
-methods are fast enough.
+@example
+@kbd{C-x C-f @trampfn{ssh, root, otherhost,/etc/motd} @key{RET}}

+
+If @option{ssh} is unavailable for whatever reason, look for other
+obvious options.  For Windows, try the @option{plink} method.  For
+Kerberos, try @option{krlogin}.
+
+For editing local files as @option{su} or @option{sudo} methods, try

-aficionados just rename their @file{~/.profile} to
-@file{~/.bash_profile} on all remote hosts, and Bob's your uncle.
-
-The @value{tramp} developers would like to circumvent this problem, so
-if you have an idea about it, please tell us.  However, we are afraid
-it is not that simple: before saying @command{exec /bin/sh},
-@value{tramp} does not know which kind of shell it might be talking
-to.  It could be a Bourne-ish shell like ksh or bash, or it could be a
-csh derivative like tcsh, or it could be zsh, or even rc.  If the
-shell is Bourne-ish already, then it might be prudent to omit the
-@command{exec /bin/sh} step.  But how to find out if the shell is
-Bourne-ish?
+When the remote host's @file{.profile} is also used for shells other
+than Bourne shell, then some incompatible syntaxes for commands in
+@file{.profile} may trigger errors in Bourne shell on the host and may
+not complete client's @value{tramp} connections.
+
+One example of a Bourne shell incompatible syntax in @file{.profile}:
+using @command{export FOO=bar} instead of @command{FOO=bar; export
+FOO}.  After remote login, @value{tramp} will trigger an error during
+its execution of @command{/bin/sh} on the remote host because Bourne
+shell does not recognize the export command as entered in
+@file{.profile}.
+
+Likewise, (@code{~}) character in paths will cause errors because
+Bourne shell does not do (@code{~}) character expansions.
+
+One approach to avoiding these incompatibilities is to make all
+commands in @file{~/.shrc} and @file{~/.profile} Bourne shell
+compatible so @value{tramp} can complete connections to that remote.
+To accommodate using non-Bourne shells on that remote, use other
+shell-specific config files.  For example, bash can use
+@file{~/.bash_profile} and ignore @file{.profile}.
