Hi.  I made simple shared library for extracting information of
options by overrinding getopt_long.

Z(4):akr@serein% make
gmake: `optioninfo.so' is up to date.
Z(4):akr@serein% _ls_arguments=($(LD_PRELOAD=$PWD/optioninfo.so ls))
Z(4):akr@serein% _ls () { _arguments $_ls_arguments '*:file: _files' }
Z(4):akr@serein% compdef _ls ls                                       
Z(4):akr@serein% ls -<TAB>

Although this is not so sophisticated now and it is not portable, it
is very useful in some case.  How about this?
