Short CVS question

Hi,

I have a short CVS question please: How do I go from a particular file 
revision like

pgsql/cvs/pgsql/src/backend/parser/parse_relation.c.1.3

to the complete commit? I.e. I would like to navigate back from this 
particular file to the commit and see all the other files that were 
touched by the commit.

Thanks!

Dirk
