+# Take an OpenStack translated portable object (*.po) file and translate
+# all of the message strings back into English using Google Translate.
+# Allows for a quick examination of the translation.
+#
+# Each translated message has the following format:
+#
+#    msgid "Confirm Delete Instance"
+#    msgid_plural "Confirm Delete Instances"     (Optional)
+#    msgstr "Подтвердите удаление инстанса"      (Optional)
+#    msgstr[0] "Подтвердите удаление инстанса"   (Optional)
+#    msgstr[1] "Подтвердите удаление инстансов"  (Optional)
+#    msgstr[2] "Подтвердите удаление инстансов"  (Optional)
+#
+# This gives us:
+# - The original message in the "msgid/msgid_plural" line(s).
+# - The translated message in the "msgstr/msgstr[*]" line(s).
+#
+# After untranslating, we will output the following:
+# - The "msgid/msgid_plural" line(s).
+# - The "msgstr/msgstr[*]" line(s).
+# - The translation of the "msgstr/msgstr[*]" line(s).
+#
+# The engine of this script is "trans" (which itself uses gawk). We will
+# need to install "trans" for this script to work.
+#     % wget git.io/trans
+#     % chmod a+x trans
+#  Make sure the "trans" script is in your PATH.
