The static library implementing this backend. This environment variable specifies the list of directories that may contain the configuration file. If the value of the environment variable ends with the directory separator character, then the default directories are searched after the explicitly spec ified directories. If the library was compiled with debug support enabled, this environment variable controls the debug level for this backend. E.g., a value of 255 requests all debug output to be printed.
Smaller levels reduce verbosity.
However with this release I almost complete the gui part of all scanners. Most of the functionality is there. My personal belief is that with a slight touch of debugging the OneScanner could be actually usable. The ColorOneScanner needs more work. AppleScanner is of course almost fully supported.
