-:NOTE: This file is source'd, so be careful when editing.
------
-=== packages.conf ===
-Die Clusterpakete werden in der Datei, die durch PAKETE in der
-/etc/sccl/sccl.conf angegeben ist, definiert. Als Standard ist
-/etc/sccl/packages.conf festgelegt. Sie beinhaltet eine Tabelle mit allen Paketen
-des Clusters und die Clusterknoten, auf denen sie gestartet werden dürfen.
-  # vi /etc/sccl/packages.conf
-  package1 clnode1 clnode2
-  package2 - clnode2 clnode1
-  package3 - clnode2 clnode1
-Jede Zeile hat die Form:
-  <package> { - | <stdnode> } [<altnode1> <altnode2> ...]
-Das Clusterpaket <package> wird automatisch beim Start des Clusters auf
-seinem Standard-Clusterknoten <stdnode> gestartet und darf auf allen
-<altnodeX> laufen. Ein '-' anstelle von <stdnode> verhindert das
-automatische Starten des Clusterpakets beim Starten des Clusters oder des
-Clusterknotens.
------
-=== resources.conf ===
-The resources are configured in the file indicated by the (showing the default entry):
-  RESOURCES=/etc/sccl/resources.conf
-entry in the ''/etc/sccl/sccl.conf''.
-The RESOURCES file contains all definitions of the resources belonging to the cluster packages.
-It may also contain resource definitions belonging to sub-packages which are **not** listed
-as packages in the PACKAGES file but only used in the RESOURCES file. Sub-packages are used to
-bundle resources under one definition, which is useful if several packages make use of that sub-package.
-Sub-packages cannot be started stand-alone and they do not appear as package in the output of the
-''sccl_show_cluster'' command and their status cannot be determined.
-The resource definition **must** be in one line!
-The general syntax of a resource definition:
-  <package> <description_no_spaces> [MULTI] <resource> <resource> ...
-When the package ist "started", all resources are activated or started in the sequence
-the resources are given in the resource definition line (from left to right/forward).
-When the package ist "stopped", all resources are deactivated or stopped in the sequence
-the resources are given in the resource definition line (from right to left/backwards).
-{|
