+'''
+Forked version of lookup.py by Georg Pfuetzenreuter <georg+salt@lysergic.dev>.
+Notable changes:
+    - Python 3 support
+    - nested pillar lookups
+Original: https://github.com/vmware-archive/salt-contrib/blob/master/pillars/lookup.py
+
+Look up data from other pillar values or by executing a module function.
+
+Usage:
+
+Generally, this module should be configured as the final ext_pillar, if other
+ext_pillars are used.
+
+A pillar value matching the pattern ${...} will trigger this module to perform
+a lookup. A lookup may be a pillar value (e.g., ${other_value}) or a call to
+an execution module (${cmd.run('echo "foo"')}). Note that module functions are
+executed on the master. Nested functions are supported, as is the passing of
+a pillar value to a function. E.g.: ${cmd.run(command)}
