-#GtkText is deprecated and unsupported. It is known to be
-buggy. To use it, you must define the symbol %GTK_ENABLE_BROKEN
-prior to including the GTK+ header files. Use #GtkTextView instead.
-</para>

-A #GtkText widget allows one to display any given text and manipulate it
-by deleting from one point to another, selecting a region, and various
-other functions as outlined below. It is inherited from #GtkEditable.

-<!-- ##### FUNCTION gtk_text_new ##### -->
-<para>
-Creates a new #GtkText widget, initialized with the given pointers to
-#GtkAdjustments. These pointers can be used to track the viewing position
-of the #GtkText widget. Passing %NULL to either or both of them will make
-the #GtkText create its own. You can set these later with the function
-gtk_text_set_adjustment().
-</para>
-
-@hadj: horizontal adjustment.
-@vadj: vertical adjustment.
-@Returns: the new #GtkText widget.
-
-
-<!-- ##### FUNCTION gtk_text_set_editable ##### -->
-<para>
-Sets whether the #GtkText widget can be edited by the user or not. This
-still allows you the programmer to make changes with the various #GtkText
-functions.
-</para>
-
-@text: the #GtkText widget
-@editable: %TRUE makes it editable, %FALSE makes it immutable by the user
-
-
-<!-- ##### FUNCTION gtk_text_set_word_wrap ##### -->
-<para>
-Sets whether the #GtkText widget wraps words down to the next line if it
-can't be completed on the current line.
-</para>
-
-@text: the #GtkText widget
-@word_wrap: %TRUE makes it word wrap, %FALSE disables word wrapping
-
-
-<!-- ##### FUNCTION gtk_text_set_line_wrap ##### -->
-<para>
-Controls how #GtkText handles long lines of continuous text. If line wrap
-is on, the line is broken when it reaches the extent of the #GtkText widget
-viewing area and the rest is displayed on the next line. If it is not set,
-the line continues regardless size of current viewing area. Similar to word
-wrap but it disregards word boundaries.
-</para>
-
-@text: the #GtkText widget
-@line_wrap: %TRUE turns line wrap on, %FALSE turns it off
-
-
-<!-- ##### FUNCTION gtk_text_set_adjustments ##### -->
-<para>
-Allows you to set #GtkAdjustment pointers which in turn allows you to
-keep track of the viewing position of the #GtkText widget.
-</para>
-
-@text: the #GtkText widget
-@hadj: the horizontal adjustment
-@vadj: the vertical adjustment
-
-
-<!-- ##### FUNCTION gtk_text_set_point ##### -->
-<para>
-Sets the cursor at the given point. In this case a point constitutes
-the number of characters from the extreme upper left corner of the #GtkText
-widget.
-</para>
-
-@text: the #GtkText widget
-@index: the number of characters from the upper left corner
-
-
-<!-- ##### FUNCTION gtk_text_get_point ##### -->
-<para>
-Gets the current position of the cursor as the number of characters from
-the upper left corner of the #GtkText widget.
-</para>
-
-@text: the #GtkText widget
-@Returns: the number of characters from the upper left corner
-
-
-<!-- ##### FUNCTION gtk_text_get_length ##### -->
-<para>
-Returns the length of the all the text contained within the #GtkText widget;
-disregards current point position.
-</para>
-
-@text: the #GtkText widget
-@Returns: the length of the text
-
-
-<!-- ##### FUNCTION gtk_text_freeze ##### -->
-<para>
-Freezes the #GtkText widget which disallows redrawing of the widget until
-it is thawed. This is useful if a large number of changes are going to
-made to the text within the widget, reducing the amount of flicker seen
-by the user.
-</para>
-
-@text: the #GtkText widget
-
-
-<!-- ##### FUNCTION gtk_text_thaw ##### -->
-<para>
-Allows the #GtkText widget to be redrawn again by GTK.
-</para>
-
-@text: the #GtkText widget
-
-
-<!-- ##### FUNCTION gtk_text_insert ##### -->
-<para>
-Inserts given text into the #GtkText widget with the given properties as
-outlined below.
-</para>
-
-@text: the #GtkText widget
-@font: the #GdkFont to use
-@fore: the foreground color to insert with
-@back: the background color to insert with
-@chars: the actual text to be inserted
-@length: the length of the text to be inserted, passing -1 makes it insert
-all the text.
-
-
-<!-- ##### FUNCTION gtk_text_backward_delete ##### -->
-<para>
-Deletes from the current point position backward the given number of
-characters.
-</para>
-
-@text: the #GtkText widget
-@nchars: the number of characters to delete
-@Returns: %TRUE if the operation was successful, otherwise returns %FALSE
-
-
-<!-- ##### FUNCTION gtk_text_forward_delete ##### -->
-<para>
-Deletes from the current point position forward the given number of
-characters.
-</para>
-
-@text: the #GtkText widget
-@nchars: the number of characters to delete
-@Returns: %TRUE if the operation was successful, otherwise returns %FALSE
-
-
-<!-- ##### MACRO GTK_TEXT_INDEX ##### -->
-<para>
-Returns the character at the given index within the #GtkText widget.
-</para>
-
-@t: the #GtkText widget
-@index: the number of characters from the upper left corner
