Sorry to resurrect an old thread, but seeing libzlibrary in my N900's Application Manager frustrated me.

The original use case, outlined in the original posts (being able to download a few debs and install them offline) is not met by putting libzlibrary in user/. Maemo 5's Application Manager has no option to install from individual files.

The only solution for the offline install requirement is something along the lines of a deb which contains other debs and installs/uninstalls them in its postinst/prerm. This does not require any special section for FBReader's library.
