+# WARNING: send_mail.py requires a companion app.ini file provided by Abner. Without it the script will crash!
+
+# QUICK NOTES:
+#
+# 1. This script is for Handmade meetup hosts. You can email a meetup invite to your group like so:
+#
+# > python3 send_mail.py --subject SUBJECT --body BODY
+#
+# where SUBJECT is the subject of your email and BODY is the file containing its contents. Plain text or HTML is supported
+#
+# 2. Your emails automatically include fancy Handmade Cities branding with unsubscribe links
+#
+# 3. You can dump the mailing list of your meetup group so far:
+#
+# > python3 send_mail.py --dump
+#
+# This list grows automatically as more people sign up for your city (at handmadecities.com/meetups)
