    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..
