The rsfbook repository was getting too big with large figures and movies and that created a lot of difficulties. In a major reorganization effort, we have moved the human-edited part of the books (LaTeX and SConstruct files) under /rsf/book and created a separate repository rsffigs just for figures.
Checkout the figure repository as follows:
svn co $RSFROOT/figs.
You can also use a different path and set the RSFFIGS environmental variable. The usual scons test and scons lock commands should work.
