Directories tree in package

[Narcis Garcia <debianlists@actiu.net>]

I'm currently building ntfsundelete-tree package with the main file
specified at debian/install:
ntfsundelete-tree usr/sbin

- If I specify more files by this way, will do APT uninstaller remove
empty directories of those files?
eg.:
icon.png usr/share/ntfsundelete-tree

- Is this specification compatible with RPM (when porting with Alien)?

- How to do for empty directories creation?
