As adu is based on libosl, the object storage layer, you first have to install libosl. Adu's command line parser and the interactive help are generated using gnu gengetopt. You'll likely need a ftp://ftp.gnu.org/pub/gnu/gengetopt/ (recent version) to compile adu from source. In order to generate the man page, ftp://ftp.gnu.org/pub/gnu/help2man (help2man) must be installed. For the html version of the man page, http://www.triptico.com/software/grutatxt.html (grutatxt) is used. The fancy logo was generated using skencil.
