%description
Utilities and library for creating and applying binary patches to file system directories.
It's based on Javaxdelta library - java implementation of xdelta binary diff algorithm.
GDIFF format is used for patches.
Note: javaxdelta depends on GNU Trove 1.0.2 library which is released under the LGPL license.
This project is released under the MIT License (the same license is used by javaxdelta project).

%description -l pl
Narzędzia i biblioteki do tworzenia i nakładania binarnych łatek różnicowych na katalogi w systemie plików.
Projekt bazuje na bibliotece Javaxdelta - implentacji algorytmu binarnych łatek różnicowych xdelta dla języka Java.
W łatkach wykorzystywany jest format GDIFF.
Uwaga: javaxdelta zależy od biblioteki GNU Trove 1.0.2 która została wydana na licencji LGPL.
Ten projekt został wydany na licencji MIT (takiej samej licencji jaka jest używana przez projekt javaxdelta).
