japhar-config

[Brian Jones]

Any problem with japhar-config.in written as this?  (it works, just
want to make sure everyone is okay with this as it is more akin to
guile-config and includes more information (which I need)).  Of course if 
I'm the only person using japhar-config, there should be no problems!
