[erlang-questions] Best way to check if a given directory is empty (or not)?

[Miles Fidelman]

um...

given an empty directory:

7> file:list_dir("/Users/mfidelman/empty") == {ok,[]}.
true

given a non-empty directory:
8> file:list_dir("/Users/mfidelman") == {ok,[]}.
false

note:
file:list_dir seems to do the right thing with invisible files - with an 
invisible file in ../empty
9> file:list_dir("/Users/mfidelman/empty") == {ok,[]}.
false
10> file:list_dir("/Users/mfidelman/empty").
{ok,[".foo"]}
