Warning: if you uncomment the next line you 'll get

zero functionality. All the scanner specific function
|
|
such as sane_read, attach and the others will return
|
|
without doing anything. This way you can run the backend
|
|
without an attached scanner just to see if it gets
|
|
its control variables in a proper way.
|
|
|
|
TODO: This could be a nice thing to do as a sane config
|
|
option at runtime. This way one can debug the gui-ipc
|
|
part of the backend without actually has the scanner.
