No, the chunk.sections parameter was replaced with
chunk.section.depth about 8 months later.

See this reference for more help on chunking
with XSL:

The proper syntax for the command line option is:

--stringparam chunk.section.depth 0

You could create a stylesheet customization file and
use xsl:include to include the updated files.  See this
reference for creating a customization file:

http://www.sagehill.net/xml/docbookxsl/CustomMethods.html#CustomDriverFile

But I don't recommend a beginner update their stylesheet
installation from CVS unless it is really necessary.
At any given time the CVS files may have been edited and
may not work with your other installed files.  With one
of the distributions (like 1.60.1), at least all the files
have been tested together.
