+facilitate the common operations with sizes in bytes.  Many projects need to
+work with sizes in bytes (be it sizes of storage space, memory...) and all of
+them need to deal with the same issues like:
+
+@itemize
+@item How to get a human-readable string for the given size?
+@item How to store the given size so that no significant information is lost?
+@item If we store the size in bytes, what if the given size gets over the
+MAXUINT64 value?
+@item How to interpret sizes entered by users according to their locale and
+typing conventions?
+@item How to deal with the decimal/binary units (MB versus MiB) ambiguity?
+@end itemize
+
+@code{libbytesize} offers a generally usable solution that could be used by
+every project that needs to deal with sizes in bytes.  It is written in the C
+language with thin bindings for other languages.")
