Gaphr ndi uml ndi sysml njira yolembera ku Python. Tinapanga kuti zikhale zosavuta kugwiritsa ntchito, ngakhalebe zamphamvu. Gaphr amayambitsa mtundu wogwirizana ndi uml 2, kotero ndi chida choposa chithunzi chojambula. Mutha kugwiritsa ntchito Gaphr kuti muwonetsetseko magawo osiyanasiyana a kachitidwe komanso kupanga mitundu yokwanira, yovuta kwambiri.

Gafur adapangidwa mozungulira mfundo zotsatirazi:

• Kuphweka: Kuphweka kuyenera kukhala kosavuta kugwiritsa ntchito. Chidziwitso chokha chokha cha UML kapena Sysml chikufunika.
• Kusasinthika: Uml ndi chilankhulo chofananira, kotero mitundu yonse imatha kujambula.
• Kugwira ntchito: Kugwiritsa ntchito sikuyenera kuvutitsa wogwiritsa ntchito nthawi iliyonse amachita zinthu zosakhala uml-ish.
