sane\-escl \- SANE backend for eSCL scanners
.SH DESCRIPTION
The
.B sane\-escl
library implements a SANE (Scanner Access Now Easy) backend that
provides access to eSCL protocol scanners.

The "escl" backend for SANE supports AirScan/eSCL devices that announce
themselves on mDNS as _uscan._utcp or _uscans._utcp.
If the device is available, the "escl" backend recovers these capacities.
The user configures and starts scanning.
A list of devices that use the eSCL protocol can be found at
.IR https://support.apple.com/en-us/HT201311 .
While these devices are expected to work, your mileage may vary.

.SH FILES
.TP
.I /etc/sane.d/escl.conf
The backend configuration file.
.TP
.I /usr/lib/x86_64-linux-gnu/sane/libsane\-escl.a
The static library implementing this backend.
.TP
.I /usr/lib/x86_64-linux-gnu/sane/libsane\-escl.so
The shared library implementing this backend (present on systems that
support dynamic loading).
.SH ENVIRONMENT
.TP
.B SANE_DEBUG_ESCL
If the library was compiled with debug support enabled, this
environment variable controls the debug level for this backend.  E.g.,
a value of 128 requests all debug output to be printed.  Smaller
levels reduce verbosity.
