-**Tools.** The `OBITools3` offer the same tools as the original `OBITools`. Eventually, new versions of `ecoPrimers` (PCR primer design) [3], `ecoPCR` (*in silico* PCR) [4], as well as `Sumatra` (sequence alignment) and `Sumaclust` (sequence alignment and clustering) [5] will be added, taking advantage of the database structure developed for the `OBITools3`.

-**Implementation and disponibility.** The lower layers managing the DMS as well as all the compute-intensive functions are coded in `C99` for efficiency reasons. A `Cython` (<http://www.cython.org>) object layer allows for a simple but efficient implementation of the `OBITools3` commands in `Python 3.5`. The `OBITools3` are now being released, check the wiki for more information.
