Google Summer of Code 2013
OSGeo4W needs to incorporate several functionalities or linking to libraries such as ECW, MrSID, Oracle Client, and ESRI FileG DB which need to be asked to end users for a license. It also adds improvements to the current installer to port 64 bits machines (Windows 7, Windows Server 2012, Windows 8 etc). OSGeo4W will be extended to include a way of providing a textual license agreement(User license Policy) because the users need to agree before complete the installation.
