   1. Check the build requirements: Linux, MacOS X, Windows.
      Warning: Nvu and KompoZer are based upon Gecko 1.7 (aviary branch)...

   2. Get the code tarball here:
        http://prdownloads.sourceforge.net/kompozer/kompozer-*-src.tar-bz2?download

   3. Unzip the source:
        tar xfj kompozer-*-src.tar.bz2

   4. Edit the mozilla/.mozconfig file according to your wishes and system configuration.
      This default .mozconfig file is the one I've used to build KompoZer on Slackware (ZenWalk 4.6.1).
      There are mozconfig files for Fedora, Linspire, Debian/Ubuntu, MacOS X and Windows in the mozilla/composer/config directory.

   5. Build the code:
        make -f client.mk build_all

   6. Test your build in the mozilla/dist/bin directory.
