Terminal-specific Initialization
--------------------------------

   Each terminal type can have a Lisp library to be loaded into Emacs
when it is run on that type of terminal.  For a terminal type named
TERMTYPE, the library is called `term/TERMTYPE' and it is found by
searching the directories `load-path' as usual and trying the suffixes
`.elc' and `.el'.  Normally it appears in the subdirectory `term' of
the directory where most Emacs libraries are kept.

   The usual purpose of the terminal-specific library is to map the
escape sequences used by the terminal's function keys onto more
meaningful names, using `function-key-map'.  See the file
`term/lk201.el' for an example of how this is done.  Many function keys
are mapped automatically according to the information in the Termcap
data base; the terminal-specific library needs to map only the function
keys that Termcap does not specify.

   When the terminal type contains a hyphen, only the part of the name
before the first hyphen is significant in choosing the library name.
Thus, terminal types `aaa-48' and `aaa-30-rv' both use the library
`term/aaa'.  The code in the library can use `(getenv "TERM")' to find
the full terminal type name.

   The library's name is constructed by concatenating the value of the
variable `term-file-prefix' and the terminal type.  Your `.emacs' file
can prevent the loading of the terminal-specific library by setting
`term-file-prefix' to `nil'.

   Emacs runs the hook `term-setup-hook' at the end of initialization,
after both your `.emacs' file and any terminal-specific library have
been read in.  Add hook functions to this hook if you wish to override
part of any of the terminal-specific libraries and to define
initializations for terminals that do not have a library.  Note:
Hooks.
