on windows, i also have to take "desktop.ini" files into consideration, and
on mac there are ".DS_Store" files; none of these are truly directory
contents, but rather for directory configuration;

=E2=80=8B=E2=80=8B
ignores =3D [ '..', '.', 'desktop.ini', '.DS_Store' ]

and there are even more .files and .directories on *nix, graphical *nix and
virtual *nix systems, none of which are truly directory contents;

On IRC someone asked how to find out if a directory is empty or not, from w=
ithin ruby.<br>
<br>
It seems as if there was no simple way.<br>
<br>
I suggest adding `Dir.empty?`<br>
<br>
On IRC, someone else suggested this:<br>
<br>
~~~ruby<br>
Dir.entries(dir).size =3D=3D 2<br>
~~~<br>
<br>
I do not know if there are better ways but possibly that could<br>
be used for a `Dir.empty?` functionality?<br>
