Subject: Added CSV dumps: per filetype and per changeset
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Two new dumps were added: per filetype and for every changeset.
It necessary to set a prefix where to dump the data in csv,
because it will be generated one csv file per file type.

Now it is possible to get statistics per code, documentation,
build scripts, translations, multimedia and developers
documentation.  This feature is useful for repositories where
there are different types of file, rather than code.

The detailed information does not use the Aggregate parameter.
