;;; Site Customization
;;
;; The following variables are likely to need to be changed for your
;; site. You should do this with customize. Here is the beef: If you
;; want to print, TeX-print-command must be non-nil (if it is nil,
;; you'll get a complaint when using the print menu). If you want to
;; view the queue, TeX-queue-command needs to be non-nil (if it is
;; nil, it won't get mentioned in the menu). If TeX-printer-list is
;; nil, nothing else gets asked: the menu entries lead directly to the
;; respective commands. If those commands contain %p, the value of
;; TeX-printer-default gets inserted there, no questions asked. Now
;; if TeX-printer-list is non-nil, you'll always get asked which
;; printer you want to use. You can enter a configured printer from
;; TeX-printer-list, or an unknown one. The respective menus will
;; show all configured printers. Since you can enter unknown
;; printers, the printer name _must_ be set with %p in
;; TeX-print-command.
;; How to print.

"List of commands to execute on the current document.
Each element is a list, whose first element is the name of the command
as it will be presented to the user.
The second element is the string handed to the shell after being
expanded. The expansion is done using the information found in
`TeX-expand-list'.
The third element is the function which actually start the process.
Several such hooks has been defined:
TeX-run-command: Start up the process and show the output in a
separate buffer. Check that there is not two commands running for the
same file. Return the process object.
TeX-run-format: As `TeX-run-command', but assume the output is created
by a TeX macro package. Return the process object.
TeX-run-TeX: For TeX output.
TeX-run-interactive: Run TeX or LaTeX interactively.
TeX-run-BibTeX: For BibTeX output.
TeX-run-compile: Use `compile' to run the process.
TeX-run-shell: Use `shell-command' to run the process.
TeX-run-discard: Start the process in the background, discarding its
output.
TeX-run-background: Start the process in the background, show output
in other window.
TeX-run-silent: Start the process in the background.
TeX-run-dviout: Special hook for the Japanese dviout previewer for
PC-9801.
To create your own hook, define a function taking three arguments: The
name of the command, the command string, and the name of the file to
process. It might be useful to use `TeX-run-command' in order to
create an asynchronous process.
If the fourth element is non-nil, the user will get a chance to
modify the expanded string.
The fifth element indicates in which mode(s) the command should be
present in the Command menu. Use t if it should be active in any
mode. If it should only be present in some modes, specify a list with
the respective mode names.
Any additional elements get just transferred to the respective menu entries.

First argument SYMBOL is the name of the macro.
If called with no additional arguments, insert macro with point

match an argument to the TeX macro. What is done depend on the
type of ARGS:
string: Use the string as a prompt to prompt for the argument.
number: Insert that many braces, leave point inside the first.
nil: Insert empty braces.
t: Insert empty braces, leave point between the braces.
other symbols: Call the symbol as a function. You can define
your own hook, or use one of the predefined argument hooks. If
you add new hooks, you can assume that point is placed directly
after the previous argument, or after the macro name if this is
the first argument. Please leave point located after the
argument you are inserting. If you want point to be located
somewhere else after all hooks have been processed, set the value
of `exit-mark'. It will point nowhere, until the argument hook
set it. By convention, these hooks all start with `TeX-arg-'.
list: If the car is a string, insert it as a prompt and the next
element as initial input. Otherwise, call the car of the list
with the remaining elements as arguments.
vector: Optional argument. If it has more than one element,
parse it as a list, otherwise parse the only element as above.
