releng_5

Hello,

the handbook lists available cvs branch tags in
http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/cvs-tags.html

There are listed RELENG_5_0, RELENG_5_1 and RELENG_5_2 but not
RELENG_5. If a nonexistent tag is specified in the cvsup file
running cvsup the will delete the whole target tree.

Is RELENG_5 already available?
Is there a means to list available cvs tags without the risk of
deleting the target tree?
Which is the tag now that will approach RELENG_5_3_0_RELEASE?
