== Running OsmoSGSN

The OsmoSGSN executable (`osmo-sgsn`) offers the following command-line
options:


=== SYNOPSIS

	Print the compile-time version number of the OsmoSGSN program
*-d, --debug 'DBGMASK','DBGLEVELS'*::

	deprecated by VTY based logging configuration, see <<logging>>
	for more information.

	been deprecated by VTY based logging configuration, see
