 ;;
-;; These functions must follow a strict naming convention:
-;; `org-BACKEND-TYPE' where, obviously, BACKEND is the name of the
-;; export back-end and TYPE the type of the element or object handled.
+;;    Contents, when not nil, are stripped from any global indentation
+;;    (although the relative one is preserved).  They also always end
+;;    with a single newline character.
 ;;
-;; Moreover, two additional functions can be defined.  On the one
-;; hand, `org-BACKEND-template' returns the final transcoded string,
-;; and can be used to add a preamble and a postamble to document's
-;; body.  It must accept two arguments: the transcoded string and the
-;; property list containing export options.  On the other hand,
-;; `org-BACKEND-plain-text', when defined, is to be called on every
-;; text not recognized as an element or an object.  It must accept two
-;; arguments: the text string and the information channel.
+;;    If, for a given type, no function is found, that element or
+;;    object type will simply be ignored, along with any blank line or
+;;    white space at its end.  The same will happen if the function
+;;    returns the nil value.  If that function returns the empty
+;;    string, the type will be ignored, but the blank lines or white
+;;    spaces will be kept.
+;;
+;;    In addition to element and object types, one function can be
+;;    associated to the `template' symbol and another one to the
+;;    `plain-list' symbol.  The former returns the final transcoded
+;;    string, and can be used to add a preamble and a postamble to
+;;    document's body.  It must accept two arguments: the transcoded
+;;    string and the property list containing export options.  The
+;;    latter, when defined, is to be called on every text not
+;;    recognized as an element or an object.  It must accept two
+;;    arguments: the text string and the information channel.
+;;
+;; 2. Optionally define a variable, `org-BACKEND-option-alist', in
+;;    order to support new export options, buffer keywords or
+;;    "#+OPTIONS:" items specific to the back-end.  See
+;;    `org-export-option-alist' for supported defaults and syntax.
+;;
+;; 3. Optionally define a variable, `org-BACKEND-filters-alist', in
+;;    order to apply developer filters.  See "The Filter System"
+;;    section in this file for more information.
+;;
+;; If the new back-end shares most properties with another one,
+;; `org-export-define-derived-backend' can be used to simplify the
+;; process.
 ;;
 ;; Any back-end can define its own variables.  Among them, those
 ;; customizables should belong to the `org-export-BACKEND' group.
-;; Also, a special variable, `org-BACKEND-option-alist', allows to
-;; define buffer keywords and "#+options:" items specific to that
-;; back-end.  See `org-export-option-alist' for supported defaults and
-;; syntax.
 ;;
 ;; Tools for common tasks across back-ends are implemented in the
 ;; penultimate part of this file.  A dispatcher for standard back-ends
 ;; is provided in the last one.
