Trim directory to search?

[Peng Yu]

Hi,

I don't want to let find search directories with a file .ignore (i.e.,
anything in the directory (including the subdirectories) is ignored).
Is there an efficient way to customize find in this way? (I can think
of an simple way---recursively call "find" with maxdepth 1 and not go
into directories with .ignore. But this is not efficient.) Thanks.
