"*How ECB displays bucket-nodes in a ECB tree-buffer.
Bucket-nodes have only one job: Nodes with similar properties will be dropped
into one bucket for such a common property and all these nodes will be added
as children to the bucket-node. Besides being expandable and collapsable a
bucket-node has no senseful action assigned. Examples for bucket-nodes are
\"[+] Variables\", \"[+] Dependencies\" etc. in the Methods-buffer or buckets
which combine filenames with same extension under a bucket-node with name this
extension.
This option defines how bucket-node should be displayed. The name of the
bucket-node is computed by ECB but you can define a prefix, a suffix and a
special face for the bucket-node
The default are empty prefix/suffix-strings and 'ecb-bucket-node-face'. But
an alternative can be for example '\(\"[\" \"]\" nil) which means no special
face and a display like \"[+] [<bucket-name>]\"."

This means that speedbar is integrated in the ECB-frame and is displayed in
that window normally displaying the standard ECB-directories-buffer,
ECB-sources-buffer or ECB-methods-buffer.
This option takes effect in all layouts which contain either a directory
window, a sources window or a method window.
This option can have four valid values:
- nil: Do not use speedbar \(default)
- dir: Use speedbar instead of the standard directories-buffer
- source: Use speedbar instead of the standard sources-buffer
- method: Use speedbar instead of the standard methods-buffer
Note: For directories and sources a similar effect and usability is available
by setting this option to nil \(or 'method) and setting
`ecb-show-sources-in-directories-buffer' to not nil, because this combination
displays also directories and sources in one window.
`ecb-use-speedbar-instead-native-tree-buffer' is for people who like the
speedbar way handling directories and source-files or methods and want it in
conjunction with ECB."

"*Tree-buffers which stay selected after a key- or mouse-selection.
If a buffer \(either its name or the variable-symbol which holds the name) is
contained in this list then selecting a tree-node either by RET or by a
mouse-click doesn't leave that tree-buffer after the node-selection but
performes only the appropriate action \(opening a new source, selecting a
method etc.) but point stays in the tree-buffer. In tree-buffers not contained
in this option normaly a node-selection selects as \"last\" action the right
edit-window or maximizes the next senseful tree-buffer in case of a currently
maximized tree-buffer \(see `ecb-maximize-next-after-maximized-select').
The buffer-name can either be defined as plain string or with a symbol which
contains the buffer-name as value. The latter one is recommended for the
builtin ECB-tree-buffers because then simply the related option-symbol can be
used.
A special remark for the `ecb-directories-buffer-name': Of course here the
value of this option is only relevant if the name of the current layout is
contained in `ecb-show-sources-in-directories-buffer' or if the value of
`ecb-show-sources-in-directories-buffer' is 'always and the clicked ot hitted
node represents a sourcefile \(otherwise this would not make any sense)!
The setting in this option is only the default for each tree-buffer. With the
command `ecb-toggle-do-not-leave-window-after-select' the behavior of a
node-selection can be changed fast and easy in a tree-buffer without
customizing this option, but of course not for future Emacs sessions!"
