Build without warning RSvgDevice

Hi,

I'm trying to build a modified version of the package RSvgDevice, 
without warnings.

I'm having troubles with the description file. Here's the logs :
* checking Rd files ... WARNING
prepare_Rd: RSvgDevice.Rd:1: All text must be in a section

But the RSvgDevice.Rd file seems OKto me, what am I missing ?

Thanks for your help,
Matthieu Decorde
