+# This script is based on Git ciabot.pl by Petr Baudis.
+#
+#
+#
+# The script is meant to be configured using git-config with the following keys:
+#   hooks.fbi-project         the project name known to FBI
+#   hooks.fbi-component       an optional component name
+#   hooks.fbi-url-template    the template to the gitweb URL (containing @@sha1@@)
+#   hooks.fbi-emailsender     the sender address to use in the email
+#   hooks.fbi-refwidth        the width of references to show (default 7)
+#   hooks.fbi-noisy           include the entire log message in the announcement
+#   hooks.fbi-msg-template    the template for the message to be sent (default:
+#                               [@@component@@/]@@project@@: @@author@@: \
+#                               @@logmessage@@ [@@ref@@] @@url@@)
+#
+# The hook is meant ot be run either from a post-commit hook or an update hook. If run in
+# a central repository where people push to you want to run it in the update hook!
+#
+#   post-commit: It parses latest commit and current HEAD to get the information it needs.
+#
+#   update: You have to call it once per merged commit:
+#
+#       refname=$1
+#       oldhead=$2
+#       newhead=$3
+#       for merged in $(git rev-list ${oldhead}..${newhead} | tac) ; do
+#               /path/to/ciabot.bash ${refname} ${merged}
