#
# Kurze Featuritis:
# - build.sh sollte im Pfad liegen ~/bin ist eine gute Wahl ;)
# - build.sh erzeugt mit Hilfe des Makefiles in jedem smartclient Verzeichnis
#   ein tar-Archiv, überträgt dieses nach Oldwotan und baut es dort
# - Dazu muss ein ssh-pubkey in oldwotans /root/.ssh/authorized_keys gelegt 
#   werden (build.sh verwendet ssh)
# Wichtige Einstellungen:
# - Standardmäßig baut build.sh mit --clean, wenns schnell gehen soll, die 
#   Umgebungsvariable BUILD_MODE="--no-init" exportieren
# - BUILD_DIST ist standard sles7-i386, kann auch durch entsprechenden Export
#   überschrieben werden.
# - ist BUILD_ROOT nicht gesetzt baut build.sh in der Umgebung 
#   /abuild/buildsystem.oldwotan.smartclient, um nicht mit Userumgebungen zu 
#   kollidieren. 
# - die fertigen Pakete werden nach DEST_DIR (kann durch env gesetzt werden) 
#   in die vorgegebene Hierarchie (src, i386/sles/7) auf den lokalen Rechner 
#   kopiert. Vorgabe ist /tmp/smartclient_build
