daa2iso and uif2iso are two very small tools that allow to conver daa and uifs files to iso.

There are lots of documentation and example .bep files in svn on the Haikuports site.

NOTE: These tools are pretty easy to compile without any change in the source code, your job is to make a .bep file that would automate these steps using haikuporter.

The tools are available using those URLs :
