%description
Since Linux 4.8 the GPIO sysfs interface is deprecated. User space
should use the character device instead. This library encapsulates the
ioctl calls and data structures behind a straightforward API.

%description -l pl.UTF-8
Od wersja Linuksa 4.8 interfejs sysfs do GPIO jest przestarzały.
Przestrzeń użytkownika powinna zamiast niego używać urządzenia
znakowego. Ta biblioteka kryje wywołania ioctl i struktury danych za
bezpośrednim API.
