#
#     - parameters for launching are taken from SalomeApp.xml;
#     - if the config file does not exist, it is created with default values.

#  $: ${KERNEL_ROOT_DIR}/bin/salome/runSalome --modules=GEOM,SMESH,VISU,SUPERV,MED --embedded=registry,study,moduleCatalog,cppContainer --standalone=pyContainer,supervContainer --xterm --killall

#     parameters from command line supersede those from SalomeApp.xml
#
# Some CORBA servers can be launched in the SALOME_Session_Server's process
# (embedded = same process) or in a separate process (standalone):
# --> registry,study,moduleCatalog,cppContainer
# Other CORBA servers could only be launched in separate process (standalone):
# --> pyContainer,supervContainer

# l'option -i permet de garder l'interpreteur python ouvert :
