Icons of program

[Sangsu Kim <sskim ssrnet snu ac kr>]

Most file managers use icons for presenting file objects but there is no
standard method of managing icon-filetype database in UNIX world.
KDE uses MIME type database  based on the file extensions and predefined
icons for some programs.
But for the files without extension like  most other executable files,
it is not so easy to decide which icon will be used.
So if  icon information is included in executable files just like as
Windows does,
it  provides an very straight way of showing icons for executable files.

Is there any standard method of include  icons into executable file?
I think that ELF format is generous and flexible enough to include the
icon information.
