Tools need the complete XML (hierarchy_out.xml), but for humans it is quite annoying... right?
So now Genesis produces both the hierarchy_out.xml (for tools) and small_hierarchy_out.xml (for more human tools). The "small" version, still contains the entire hierarchy, but only prints tweakable parameters (i.e. skips ImmutableParameters) and also skips other meta data that most of you don't care about (thus probably half the size or less).
Note that it dumps two files so no worries if you like the full format.
For Stanford users: it is installed on /cad, so just start a new shell and source the environment. Out of Stanford, this is version r9762.
Thanks,
