+Tinderbox example for SeaMonkey build
+=====================================
+
+Here is an example of how to set up a "SeaMonkey" tinderbox
+build of mozilla.
+
+  # Create tinderbox source files in mozilla,
+  # then SeaMonkey directory where mozilla tree will live.
+  cvs co mozilla/tools/tinderbox
+  mkdir SeaMonkey
+  cd SeaMonkey; ../mozilla/tools/tinderbox/install-links
+
+  #
+  # Create tinder-config.pl file in SeaMonkey directory.  
+  # Copy one from an existing build, or create a sample one and edit it:
+  #
+  ./build-seamonkey.pl --example-config > tinder-config.pl
+
+  #
+  # mozconfig.  If you have configure options, add them to a
+  # file named "mozconfig" in the SeaMonkey directory.
+  # Again, you can copy one from a build, or create one.
+  # For a default stock build, this file is not needed or
+  # can be blank.
+  #
+
+  # Start the tinderbox!  From the SeaMonkey directory:
+  ./tinderbox depend start
+
+  # You can watch the build run the first time with:
+  tail -f <objdir>/<logname>
+
