Text Formatting ⇒ ledmac | Paragraph Numbers bold and centered

[Otinel]

Hi everybody,

I'm using ledmac to make text edition. I reach to number each paragraph which start with \pstart using the line \numberpstarttrue. Perfect.

Now I want this numbers in bold, in roman font and centered : how can I get to this ? How can I change this numbers appearance ?

Other question about it : how can change the space between this numbers and the beginning of the text ?


Thanks for your answers.

Ps : I hope my english is quite understandable because I'm french....
