Hello Gyuyoung

We were discussing this in June on webkit-dev but in more broad 
approach. See Grzegorz proposition here:

There are two arguments of keeping documentation in cpp files:
1) when developer is working on function code he will not forget about 
updating documentation which is just in front of his eyes
2) changing header file causes more cpp files to be rebuild what makes 
building time longer

Argument 2) in my opinion is not important in current times.
Argument 1) is important but I think that advantages of keeping doc in 
.h file are more important:

1) dev packages with .h files will contain description so developers 
using webkit-efl-dev package don't need to check source code of cpp 
files when they want to know how to use given API

2) doxygen can generate documentation just using webkit-ef-dev package 
so there will be no need to have WebKit sources

3) it will be consistent with structures descriptions

Summing up:
Let's do this
