+# This pre-receive hook is meant to be put in the main
+# repository of the project to detect if a commit follow
+# the rule for database updates.
+# For example, with the issue #123, second script :
+# - adding the file scripts/script_123-2.sql
+# - putting the filename in the commit msg for easier retrieval
+
+# When encountering non-UTF8 messages commit, sed may fail.
+LANG=C
+# Small attemp at making this script portable...

+# and it helps us transmit error status outside
