=======================================
Set of scripts for a SALOME application
=======================================

This document corresponds to SALOME 6.4.0

SALOME Application concept
--------------------------

See the documentation of KERNEL module for more information on SALOME
Application concept and to learn how to define your own configuration of
SALOME and run it on one or several computers. The recommended way to create
a new application is with the script appli_gen.py that can be found in KERNEL
installation. An application has probably already been generated for you if
you downloaded a binary version of SALOME.

To find all the files described below, please refer to a generated
application as some of them are generated automatically and thus are not
present in this appliskel directory.

User run scripts
----------------

The SALOME user can use the following scripts:

runAppli [DEPRECATED]
   Launches a SALOME Session
   (similar to ${KERNEL_ROOT_DIR}/bin/salome/runSalome but with a different
   name to avoid confusions).

runSession [DEPRECATED]
   Launches a shell script in the SALOME application environment, with access
   to the current SALOME session (naming service), if any.
   Without arguments, the script is interactive. With arguments, the script
   executes the command in the SALOME application environment.

runConsole [DEPRECATED]
   Gives a python console connected to the current SALOME Session.
   It is also possible to use runSession, then python.

salome [NEW]
   A single Python command to start SALOME:
   salome [start]:  replace runAppli
   salome shell:    replace runSession
   salome console:  replace runConsole


SALOME internal run scripts
---------------------------

envd
   Sets SALOME application environment, envd is sourced by other scripts.

getAppliPath.py
   Used by other scripts to define the Application Path.

For remote calls, SALOME uses one script.

runRemote.sh
   This script is mainly used to launch containers. The first 2 arguments
   define the hostname and port userd for naming service, the remaining
   arguments define the command to execute.


The following files can be adapted to your environment and SALOME Application
------------------------------------------------------------------------------

- CatalogResources.xml
- SalomeApp.xml
- env.d/atFirst.sh
- env.d/envProducts.sh
- env.d/envSalome.sh

CatalogResources.xml
   This files describes all the computers the application can use. The default
   file is minimal. A specific application directory can be set on a
   particular computer with a line::

       appliPath="my/specific/path/on/this/computer"

SalomeApp.xml
   This file is similar to the default given
   in ${GUI_ROOT_DIR}/share/salome/resources/gui


Proposal for env.d scripts
~~~~~~~~~~~~~~~~~~~~~~~~~~
Each user can define his own configuration for these scripts, following
the above rules. The generated files are good examples to start with.

envProducts.sh
    Sets the SALOME prerequisites.

configSalome.sh
    Sets all the MODULE_ROOT_DIR that can be used in the SALOME application.

configGUI.sh
    Sets variables necessary for SALOME GUI.
    SalomeAppConfig is defined by::

      export SalomeAppConfig=${HOME}/${APPLI}

    where SalomeAppConfig designates the directory containing SalomeApp.xml.
    Note that ${APPLI} is already defined by the calling scripts when
    env.d/configGUI.sh is sourced.
