+Since SALOME 7.5.0 this flag is switched ON by default.
+Several instances can be safely started concurrently. For example in an automated process, calling several times the following commands (WORK_DIR variable changes at each call):
+\code
+salome start -t --ns-port-log=${WORK_DIR}/session.log
+salome shell -p `cat ${WORK_DIR}/session.log` ${SALOME_APPLI_FOLDER}/bin/salome/waitContainers.py # may be optional
+salome shell -p `cat ${WORK_DIR}/session.log` ${BASE_DIR}/hello.py
+salome kill `cat ${WORK_DIR}/session.log`
+\endcode

+\section remote_calls Remote calls
+With \c salome \c shell user can connect to a SALOME instance running on a remote computer. In this case the options <tt>-p PORT</tt>, <tt>-m MACHINE</tt>, <tt>-d DIRECTORY</tt> and <tt>-u USER</tt> must be provided. Moreover syntax <tt>out:res1,res2,...</tt> can be used to get results back from remote machine.
+For example:
+\code
+ salome shell -m remotemachine -p 2810 -u myself -d /full/path/to/salome concatenate.py args:file1.txt,file2.txt out:result.txt
+\endcode
+In this example user <tt>myself</tt> connects to <tt>remotemachine</tt> to run the script <tt>concatenate.py</tt> in a SALOME instance running on port <tt>2810</tt>; the script takes two input parameters and produces one result file.
+The script and the input files are on the local computer. They are copied to the remote machine using a secure connection ; results produced on remote computer are transferred on the local machine using the same protocol. Script, input files and results are removed from remote machine.
