From: Max &lt;msuraev(a)sysmocom.de&gt; Introduce new configuration option bscs-config-file which includes BSC configuration from the given file. Both absolute and relative (to the main config file) paths are supported. Add 'show bsc-config' command to display current BSC configuration. Note: it is still possible to have BSC configuration in the main file (provided proper index number is used) and in runtime but BSC configuration is no longer saved automatically. The management of included configuration file is left to external tools. Update configuration examples.
