+%description
+libGringotts is a small, easy-to-use, thread-safe C library
+ originally developed for Gringotts; its purpose is to 
+encapsulate data (generic: ASCII, but also binary data) 
+in an encrypted and compressed structure, to be written 
+in a file or used elseway. It makes use of strong 
+encryption algorithms, to ensure the data are as safe 
+as possible, and allow the user to have the complete 
+control over all the algorithms used in the process.
+
+%description        -l pl
+libGringotts to niewielka, łatwa w użyciu biblioteka 
+napisana w C, początkowo tworzona dla Gringotts. 
+Jej zadaniem jest przechowywanie danych 
+(głównie: ASCII, ale równiez binarnych) w zaszyfrowanej 
+i skompresowanej strukturze, zapisywanej np. w pliku.
+Używa ona silnych algorytmów szyfrujących 
+dla maskymalnego bezpieczeństwa danych 
+oraz by zapewnić użytkownikowi pełną kontrolę nad nimi.
