"*Add path of a file to `ecb-source-path' if not already contained.
This is done during the auto. windows synchronization which happens if a file
is opened not via the file/directory-browser of ECB. In such a situation ECB
adds the path of the new file auto. to `ecb-source-path' at least temporally
for the current Emacs session. This option defines two things:
1. Should only the root-part \(which means for Unix-like systems always '/'
and for windows-like systems the drive) of the new file be added as
source-path to `ecb-source-path' or the whole directory-part? For
remote-files \(e.g. tramp, ange-ftp- or efs-files) the root-part is the
complete host-part + the root-dir at that host \(example:
/berndl@ecb.sourceforge.net:/ would be the root-part of
/berndl@ecb.sourceforge.net:/tmp/test.txt).
2. Should this path be added for future sessions too?
The value of this option is a cons-cell where the car is a boolean for 1. and
the cdr is a boolean for 2.
A value of not nil for the car \(1.) is reasonably if a user often opens files
not via the ECB-browser which are not located in any of the paths of
`ecb-source-path' because then only one path for each drive \(windows) or the
root-path \(unix) is added to the directory buffer of ECB."

not nil. So for this situation `ecb-display-default-dir-after-start' takes no
effect but this option is for the case if no file-buffer is displayed in the
edit-window after startup:
If true then ECB selects autom. the current default-directory after activation
even if no file-buffer is displayed in the edit-window. This is useful if ECB
is autom. activated after startup of Emacs and Emacs is started without a
file-argument. So the directory from which the startup has performed is auto.

"*Update an integrated speedbar after selecting a directory.
If not nil then an integrated speedbar will be updated after selecting a
directory in the ECB-directories-buffer so the speedbar displays the contents
of that directory.
Of course this option makes only sense if the integrated speedbar is displayed
in addition to the ECB-directories-buffer.
This option can have the following values:
- t: Always update speedbar.
- nil: Never update speedbar.
- auto: Update when senseful \(see scenarios below)
- <function>: A user-defined function. The function is called after a
directory is selected, gets the selected directory as argument and has to
return nil if the the integrated speedbar should NOT be updated.
Two example-scenarios where different values for this option can be senseful:
If `ecb-show-sources-in-directories-buffer' is not nil or you have a layout
where an ECB-sources-buffer is visible then you probably want to use the
ECB-directories-buffer \(and/or the ECB-sources-buffer) for directory- and
file-browsing. If you have in addition an integrated speedbar running then you
probably want to use speedbar instead of the ECB-methods-buffer for
source-content-browsing. In this case you probably want the speedbar not be
updated because you do not need speedbar reflecting the current-directory
contents but only the contents of the currently selected source-file and the
integrated speedbar updates itself autom. for the latter one!
If `ecb-show-sources-in-directories-buffer' is nil and there is also no
ECB-sources-buffer visible in the current layout then you probably want to use
an integrated speedbar for browsing directory-contents \(i.e. the files) and
file-contents \(instead of the ECB-methods-buffer for example). In this case
you probably want the speedbar updated because you need speedbar reflecting
the current-directory contents so you can select files.
The value 'auto \(see above) takes exactly these two scenarios into account."

the machine). Or if it contains remote-source-paths which means paths in the
sense of tramp, ange-ftp or efs. For these directories actualizing the
sources- and/or directories- buffer of ECB \(if displayed in current layout!)
can slow down dramatically so a caching increases speed a lot.
The value of this option is a list where the each element is a cons-cell and
looks like:

<dir-regexp>: Regular expression a directory must match to be cached.
<filenumber threshold>: Number of directory contents must exceed this number.
A directory will only be cached if and only if the directory-name matches

`ecb-cache-directory-contents-not'!
The cache entry for a certain directory will be refreshed and actualized only
by using the POWER-click \(see `ecb-primary-secondary-mouse-buttons') in the
directories-buffer of ECB.
Default-value: ECB caches the contents of all remote directories regardless of
the size and all other directories if more than 50 entries are contained.
Examples:
An entry \(\"/usr/home/john_smith/bigdir*\" . 1000) means the contents of
every subdirectory of the home-directory of John Smith will be cached if the
directory contains more than 1000 entries and its name begins with \"bigdir\".
An entry \(\".*\" . 1000) caches every directory which has more than 1000

An entry \(\"^/\\\\\(\[^:/]*@\\\\)?\\\\\(\[^@:/]*\\\\):.*\" . 0) caches every
remote \(in the sense of tramp, ange-ftp or efs) directory regardless of the

"*Static user extensions for the popup-menu of the directories buffer.
Value is a list of elements of the following type: Each element defines a new
menu-entry and is either:
a) Menu-command: A list containing two sub-elements, whereas the first is the
function \(a function symbol) being called if the menu-entry is selected
and the second is the name of the menu-entry.
b) Separator: A one-element-list and the element is the string \"---\": Then a
non-selectable menu-separator is displayed.
c) Submenu: A list where the first element is the title of the submenu
displayed in the main-menu and all other elements are either menu-commands
\(see a) or separators \(see b) or another submenu \(see c). This allows
deep nested menu-submenu-structures. Currently a level of 4 is allowed but
in general there could be an infinite depth of nesting but it makes no
sense - if possible at all - to define infinite nested defcustom-types. So
there is a limit of 4 levels but tis is not a hard limit: Just increase the
value of the `ecb-max-submenu-depth' *BEFORE* first loading ECB!
The function of a menu-command must follow the following guidelines: Such a
function must be defined with the macro `tree-buffer-defpopup-command! This
macro defines a new popup-command whereas the newly defined command gets one
argument NODE. See the docstring of `tree-buffer-defpopup-command' for further
details.
Example for the definition of such a popupmenu-command:
\(tree-buffer-defpopup-command ecb-my-special-dir-popup-function
\"Prints the name of the directory of the node under point.\"
\(let \(\(node-data=dir \(tree-node->data node)))
\(message \"Dir under node: %s\" node-data=dir)))
