S60 SDK API Plug-in Installation for GnuPoc
The SDK API Plug-in package for S60 SDKs has quite a few interesting APIs, such as the Browser Launcher API and the New File Service Client API.
Some days ago I wrote a script for installing plugins from the package onto GnuPoc style SDKs. It may be downloaded from http://www.hiit.fi/files/fi/da/gnupoc/.
