+@subsection Per-Connection Local Variables
+@cindex local variables, for all remote connections
+@cindex connection-local variables
+@cindex per-connection local variables
+
+ Most of the variables reflect the situation on the local machine.
+Often, they must use a different value when you operate in buffers
+with a remote default directory. Think about the shell to be applied
+when calling @code{shell} -- it might be @file{/bin/bash} on your
+local machine, and @file{/bin/ksh} on a remote machine.
+
+ This can be accomplished with @dfn{connection-local variables}.
+Directory and file local variables override connection-local
+variables. Unsafe connection-local variables are handled in the same
+way as unsafe file-local variables (@pxref{Safe File Variables}).
+
+@findex connection-local-set-profile-variables
+@findex connection-local-set-profiles
+ Connection-local variables are declared as a group of
+variables/value pairs in a @dfn{profile}, using the
+@code{connection-local-set-profile-variables} function. The function
+@code{connection-local-set-profiles} activates profiles for a given
+criteria, identifying a remote machine:
+
+@example
+(connection-local-set-profile-variables 'remote-ksh
+ '((shell-file-name . "/bin/ksh")
+ (shell-command-switch . "-c")))
+
+(connection-local-set-profile-variables 'remote-bash
+ '((shell-file-name . "/bin/bash")
+ (shell-command-switch . "-c")))
+
+(connection-local-set-profiles
+ '(:application tramp :machine "remotemachine") 'remote-ksh)
+@end example
+
+ This code declares two different profiles, @code{remote-ksh} and
+@code{remote-bash}. The profile @code{remote-ksh} is applied to all
+buffers which have a remote default directory matching the regexp
+@code{"remotemachine} as host name. Such a criteria can also
+discriminate for the properties @code{:protocol} (this is the Tramp
+method) or @code{:user} (a remote user name). The @code{nil} criteria
+matches all buffers with a remote default directory.
+

@kbd{M-x auto-revert-tail-mode @key{RET}} runs similarly showing
continuous output.
+@code{shell-command} uses the variables @code{shell-file-name} and
+@code{shell-command-switch} in order to determine which shell to run.
+For remote hosts, their default values are @file{/bin/sh} and
+@option{-c}, respectively (except for the @option{adb} method, which
+uses @file{/system/bin/sh}). Like the variables in the previous
+section, these variables can be changed via connection-local
+variables.
