+# fiat-crypto repository.

+# The AUTHORS file lists the copyright holders; this file
+# lists people.  For example, Google employees are listed here
+# but not in AUTHORS, because Google holds the copyright.
+#
+# When adding J Random Contributor's name to this file,
+# either J's name or J's organization's name should be
+# added to the AUTHORS file, depending on who holds the copyright.
+#
+# Names should be added to this file like so:
+#     Individual's name <submission email address>
+#     Individual's name <submission email address> <email2> <emailN>
+#
+# An entry with multiple email addresses specifies that the
+# first address should be used in the submit logs and
+# that the other addresses should be recognized as the
+# same person.
+
+# Please keep the list sorted.
