  "Styles of indentation.
Elements of this alist are of the form:

  (STYLE-STRING [BASE-STYLE] (VARIABLE . VALUE) [(VARIABLE . VALUE) ...])

where STYLE-STRING is a short descriptive string used to select a
style, VARIABLE is any Emacs variable, and VALUE is the intended value
for that variable when using the selected style.

Optional BASE-STYLE if present, is a string and must follow
STYLE-STRING.  BASE-STYLE names a style that this style inherits from.
By default, all styles inherit from the \"user\" style, which is
computed at run time.  Style loops generate errors.

Two variables are treated specially.  When VARIABLE is
`c-offsets-alist', the VALUE is a list containing elements of the
form:

  (SYNTACTIC-SYMBOL . OFFSET)

as described in `c-offsets-alist'.  These are passed directly to
`c-set-offset' so there is no need to set every syntactic symbol in
your style, only those that are different from the default.

When VARIABLE is `c-special-indent-hook', its VALUE is added to
`c-special-indent-hook' using `add-hook'.  If VALUE is a list, each
element of the list is added with `add-hook'.

Do not change this variable directly.  Use the function `c-add-style'
to add new styles or modify existing styles (it is not a good idea to
modify existing styles -- you should create a new style that inherits
the existing style).")

STYLENAME, a string, must be an existing CC Mode style - These are contained

\"Setting the style\" is done by setting CC Mode's \"style variables\" to the
values indicated by the pertinent entry in `c-style-alist'.  Other variables
might get set too.

If DONT-OVERRIDE is neither nil nor t, style variables whose default values
have been set (more precisely, whose default values are not the symbol
`set-from-style') will not be changed.  This avoids overriding global settings
done in ~/.emacs.  It is useful to call c-set-style from a mode hook in this
way.

If DONT-OVERRIDE is t, style variables that already have values (i.e., whose
values are not the symbol `set-from-style') will not be overridden.  CC Mode
calls c-set-style internally in this way whilst initializing a buffer; if
