==Keeping locked figures separate==
The command "scons lock" in the directory of a workflow will store a "locked" copy of your figures for regression testing.  Normally these figures are stored in the location pointed to by your RSFFIGS variable, and that is where the figures from the figures repository should be stored for testing in RSFSRC/book.

However, you may want to keep your private figures in a different place.  The way to do that is to temporarily change the RSFFIGS variable in the SConstruct ''before'' importing rsf.proj like this:
<syntaxhighlight lang="python">
import os
os.environ['RSFFIGS'] = 'path_to_my_private_figures'

from rsf.proj import *
</syntaxhighlight>
If you also create a RSFALTFIGS environment variable pointing to path_to_my_private_figures, then the testing script sffiglist will automatically test your figures against those in RSFALTFIGS when the sffiglist command is executed from a location outside of RSFSRC/book.
