I used to create my reports using the openerp report designer plugin into openoffice, thanks to base_report_designer module. Now I'm trying to use Aeroo reports for my reports, because it seems more easy to update, it's not using sxw extension, just odt extension. 

My question is to use it, should I just install the aeroo_reports module, or should I install aeroo reports libraries on my ubuntu 12.04 LTS server, the one hosting my openerp v7 installation ?

If these librairies are not installed, the aeroo reports modules can be installed ?

I'm asking that because I've already the aeroo_report  module installed on my openerp instance. I have a menu right now on configuration/technical/Aeroo Reports . And I was wondering If my previous installation of aeroo report libraries is correct.

Besides, when trying to create an aeroo report for an object, there is only one output format : ODF Text Document (.odt) , I want to have pdf output format, excel,... and so on. what do I need to get this outputs formats ?.

I also want that my reports generate automatically for every page a predefined header and footer, how can I do this ? 

What is the relation that aeroo reports have with webkit report ? is it usefull for headers and footers ?.
