@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.")

It provides a compiler frontend capable of parsing most of ANSI C as well as

static analyzer also called @file{sparse}.  Sparse provides a set of
annotations designed to convey semantic information about types, such as what
address space pointers point to, or what locks a function acquires or
