+#
+# You can create a new snippet in this file by typing "snip" and then hitting
+# tab.

+# An example CoffeeScript snippet to expand log to console.log:

+# '.source.coffee':
+#   'Console log':
+#     'prefix': 'log'
+#     'body': 'console.log $1'
+#
+# Each scope (e.g. '.source.coffee' above) can only be declared once.
