+# this script updates the deltachat-core sub-repository from github.
+#
+# - make sure, the deltachat-android directory is clean
+# - make sure, deltachat-core is committed successfull before calling this script
+# - the script assumes, deltachat-core is placed in the same directory as deltachat-android
+#
+# to simplify core-development, files in the submodule folder are replaced by 
+# symbolic links to ../deltachat-core afterwards
+
+# get to main directory
+cd ..
