DOCBOOK-APPS: DocBook and CVS

Hello,

is it possible to have current docbook environment plus prior
docbooks versions through the sourceforge cvs repo?

I ´cvs get´ the modules
(well.. it was ´cvs -d:pserver:[...] co ´)

docbook
dsssl
gentext
testdocs
xmlcharent
xsl

but can´t see anything prior to sgml dtd 4.1 and xml dtd 4.1.2,
and I´d like to be able to build documents written with
previous versions of docbook.

p.s. I believe that the iso8879 entities are somewhere in there,
right?

Thank You,
