Unfortunately (un)rar 3 has an obnoxious license that prohibits
reimplementation (under a different license):

   2. The unRAR sources may be used in any software to handle RAR
      archives without limitations free of charge, but cannot be used
      to re-create the RAR compression algorithm, which is proprietary.
      Distribution of modified unRAR sources in separate form or as a
      part of other software is permitted, provided that it is clearly
      stated in the documentation and source comments that the code may
      not be used to develop a RAR (WinRAR) compatible archiver.
