 Here follows short description of building and running Waterfall binaries 
with Mozilla web browser.
 
                    Unix (Solaris, Linux)

1. export/setenv WFJDKHOME='JDK_1_3_directory'
2. checkout wf_moz6 CVS module
3. put resulting wf_moz6 directory to $(MOZILLA)/modules
4. cd $(MOZILLA)/modules/wf_moz6
5. edit src/Makefile.in and set WF variable to point to the
   top of WF tree (I hope you already checkouted and built WF tree,
   if not - read building.txt). 
6. gmake 
7. pushd $(WF)/build/unix; source set_paths; popd
8. run Mozilla from the same command line prompt
 
                    Windows

1. set WFJDKHOME='JDK_1_3_directory'
2. checkout wf_moz6 CVS module
3. put resulting wf_moz6 directory to $(MOZILLA)\modules
4. cd $(MOZILLA)\modules\wf_moz6
5. edit src\makefile.win and set WF variable to point to the
   top of WF tree (I hope you already checkouted and built WF tree,
   if not - read building.txt). 
6. make -fmakefile.win 
7. set WFHOME=$(WF)\build\win32
8. run Mozilla
