emerge / emerge.py is a tool to build the kde sources and its third party requirements on MS Windows.
To start an emerge based install, checkout the sources from the svn-directory of emerge with the following command:
svn co svn://anonsvn.kde.org/home/kde/kdesupport/kdewin32/emerge
into a new kderoot directory. Copy the file kdesettings-environment.bat into the folder kderoot\etc, rename it to kdesettings.bat and change it according to your needs.
You can get 'some' help if you run:
Below the directory kderoot\emerge\portage you have the categories as subdirectories which contain individual packages.
To build every required package for e.g. kdebase enter emerge kdebase. If you want to make a dry run, add the option -p to it.
emerge is mostly usable together with the kdewin-installer but we're currently still working on some packages which are packaged in a wrong way. To use emerge with the installer, you have to change the directory_layout in the kdesettings.bat to installer (see that file for more detailed information).
