+
+# PURPOSE
+# package a combination of sfa+sface into a snow leopard dmg install disk
+# 
+# NOTES
+# we leverage the first similar packaging initially made by Baris Metin
+# 
+# REQUIREMENTS
+# sface-skel.dmg is the skeleton that has Qt and all the other third-party software
+#   it is expected to be found in the local directory
+#   should be made available on http://mirror.onelab.eu/third-party/ as well
+# the script expects the taglevels for both sfa and sface, 
+#   in order to retrieve the corresponding code and to label the resulting package properly
+#
+
+# the place to search for the  skeleton
+SKEL_REPO=http://mirror.onelab.eu/third-party
+
+sfa_GITPATH=git://git.onelab.eu/sfa.git@sfa-1.0-20
+sface_GITPATH=git://git.onelab.eu/sface.git@sface-0.1-5
+sface_GITPATH=git://git.onelab.eu/sface.git@master
+
+# hard-wired for snow-leopard for now
+arch=snow-leopard
+
+# does not affect final dmg size as it's compressed
