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.")

     "ISPC is a compiler for a variant of the C programming language, with
extensions for single program, multiple data programming.  Under the SPMD
model, the programmer writes a program that generally appears to be a regular
serial program, though the execution model is actually that a number of
program instances execute in parallel on the hardware.")
