+# This script 
+#  - clones the libigl github repo into a temporary directory
+#  - updates submodules
+#  - compiles static library
+#  - compiles tutorial
+# If any steps fail then an email is sent to a list of recipients (add yourself
+# if you'd like to be alerted to failures, see below regarding spam filters).
+#
+# You can set up an automated nightly build-check at 2:30 AM using:
+#
+#     crontab -e
+#
+# and then add the line:
+#
+#     30 2 * * * /usr/local/igl/libigl/scripts/clone-and-build.sh
+#
+# replace the path above with the **full path** to this file.

+#     report_error command output

+# Note: Most mail clients will mark these messages as spam even if the local
+# sender (e.g. ajx@luftmatratze.local) is in your contact list. To force these
+# message to be not marked as spam, create a filter.
+#
+# You can test your spam settings with
+#
+# echo "t3st 3mail" | mail -s "libigl test email" youremail@gmail.com
+#
+# This will almost certainly end up in your spam, but you can find your default
+# email address as the sender and add a filter.
