    this used to be a very simple demo application,

    but migrated into a quite nice tool, includes all kinds of 

    warning and information boxes, background processes for directory-

    reading and internationalized strings. A good example for beginners,

    on how to do things .... (and maybe how not to do things ;-, since some

    stuff is historic and was implemented at times when better mechanisms

    were not available)

    See additional information in 'doc/misc/fbrowser.doc'.

    WARNING: files edited with FileBrowser will have leading spaces (multiple-8)

             being replaced by tabs. If tabs are to be preserved at other

             positions (for example, sendmail-config files) they will be

             corrupt after being written.

    [instance variables]:

        checkDelta      <Integer>       number of seconds of check interval

                                        (looks ever so often if shown directory

                                         has changed). You may make this number

                                        higher, if your network-times are

                                        incorrect and thus, the filebrowser

                                        checks too often.

        compressTabs    <Boolean>       if true, leading spaces will be

                                        replaced by tabs when saving text

    some of the defaults (long/short list etc.) can be set by the resource file;

    see FileBrowser>>initialize for more details..
