+### Don't edit this file manually. Update it in git, if there's a good reason to do so ###
+#
+# This file is used by SSU to find out which device (or device variant) it's
+# running on, and use this information to look for device family, and device
+# specific adaptation(s). The last two values are used when resolving URLs,
+# and therefore change depending on vendor setup.
+#
+# To avoid quoting in the search strings SSU will do each checks on the
+# _value_, and return the key, if successful. The device model returned
+# my either be the device model, or a variant. Before resolving the family
+# and adaptations variants will be resolved through entries under the
+# variants category.
+#
+# Valid categories for determining the model:
+# - file.exists -- checks for existince of a file in the filesystem
+# - systeminfo.equals -- compares the model returned by QSystemInfo
+#                        with the value provided
+# - cpuinfo.contains -- searches /proc/cpuinfo for a string
+# - arch.equals -- compares with zyppers arch (like i586)
+#
+# Resolve order is:
+#  file.exists -> systeminfo.equals -> cpuinfo.contains -> arch.equals
+#
+# The found model (after resolving variants) will be used as category. The
+# following keys are valid there:
+# - family -- the device family, used for the family specific adaptation
+# - adaptations -- list of additional adaptations, shared between families
+#
+# The value of adaptations gets converted into a QStringList, which uses
+# commas as separator. If one of the adaptation names contains a comma it
+# needs to be quoted:
+#   adaptation=foo
+#   adaptation="foo, bar", baz
+#   adaptation=foo, bar, baz
+#
+# The N9x mappings should be solved through sysinfo, but that's currently
+# broken on Mer/Nemo
