back-perl docs?

[Paul Reilly <pareilly@tcd.ie>]

Good to see that 2.1.3 has the back-perl fix :)

Is there any documentation/examples on using back-perl?
There's no mention of backend modules in the manual, and
only a simple example in the source code.

Also what's the difference between the configure parameters
"--enable-perl" and "--with-perl-module" ?

Thanks

Paul
