@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.")

@item Generates a parser in C from a grammar described in a PEG.
@item Gives your parser great efficiency by packrat parsing.
@item Supports direct and indirect left-recursive grammar rules.
@end itemize
The grammar of your parser can be described in a @acronym{PEG, Parsing
Expression Grammar}.  The PEG is a top-down parsing language, and is similar
to the regular-expression grammar.  The PEG does not require tokenization to
be a separate step, and tokenization rules can be written in the same way as
any other grammar rules.")
