On the project description site is says the license of this project is GPL. From what I understand sizeOf has to be linked into an application to work. So if I were to use sizeOf in any of my programms I would have to publish the whole programm under GPL (not even Apache or BSD allowed). This just feels wierd for a tool and I think LGPL would be a much better choice. (http://en.wikipedia.org/wiki/GNU_Lesser_General_Public_License).
I am sure you have given this some thought but I would like to know if you can and would be willing to change the licese to LGPL.
