[Box Backup-dev] Building in readline support

[James O'Gorman]

Hi all,

I noticed from the new build system that GNU readline support can be 
compiled in by running

	./configure --enable-gnu-readline

But that this says not to include this in binary packages. I'm just 
after some advice on how to handle this for the FreeBSD port. I could 
disable it by default and add a knob that says WITH_READLINE - this in 
turn could then disable the ability to create a binary package (using 
NO_PACKAGE, or RESTRICTED, or something like that).

Thoughts, anyone?

James
