Great, i succeed. And the result is exactly what i want!

However, it is so so slow.

Here is a example to convert a module util from cvs to git
--------------------------------------------------------------------------------------------
$ cvssuck $CVSROOT util                   <1>
$ mkdir util/CVSROOT                        <2>
$ edit cvs2svn-git.options and cvs2svn-example.options
   ( change run_options.add_project and ctx.cvs_log_decorder)
$ cvs2svn --options=cvs2svn-git.options
$ mkdir util.git && cd util.git && git init
$ cat ../cvs2svn-tmp/git-{blob,dump}.dat  | git-fast-import
-------------------------------------------------------------------------------------------
<1> very slow, about 30 minutes for a very small module.
       Other steps are fast enough.
<2> I have to create a dir util/CVSROOT to avoid the error
"util is not a CVS repository, nor a path within a CVS repository.  A
CVS repository contains a CVSROOT directory within its root
directory."
