22/** \class PositionalOptions
23 *
24 *  The meaning of a positional option depends on its position and its related
25 *  positions with the other positional options. There are four kinds of
26 *  positional options:
27 *   1. Inputs, object files, such as /tmp/XXXX.o
28 *   2. Namespecs, short names of libraries. A namespec may refer to an archive
29 *      or a shared library. For example, -lm.
30 *   3. Attributes of inputs. Attributes describe inputs appears after them.
31 *      For example, --as-needed and --whole-archive.
32 *   4. Groups. A Group is a set of archives. Linkers repeatedly read archives
33 *      in groups until there is no new undefined symbols.
34 *   5. Definitions of symbols. --defsym option depends on
