+ * (1) string to be matched against runtime machine's sysctl output.
+ * can be either the exact string or a substring contained
+ * within sysctl strings. no "guesses" here, a match should
+ * reliably indicate the chassis/icon.
+ *
+ * (2) string describing chassis type divulged by (1).
+ * must be one of "desktop", "laptop", "server",
+ * "tablet", "handset", "vm", "container" or NULL
+ * if only icon string can be ascertained. "vm" refers
+ * to operating systems running on baremetal hypervisors
+ * (hardware virtualization, like XEN) while "container"
+ * refers to OSs running on shared hypervisors like
+ * virtualbox or VMware. consider the distinction carefully
+ * as common virtualization software like KVM may share
+ * characteristics of both "vm" and "container" types.
+ *
+ * (3) string specifying icon to use. follows XDG icon spec.
+ * see http://standards.freedesktop.org/icon-naming-spec/icon-naming-spec-latest.html
+ * for allowed strings.
+ *
+ * (4) chassis precedence bit. TRUE if (2) is defined and
+ * we're certain it is the proper string. FALSE in the
+ * circumstance (2) may be the correct string, unless
+ * a match with this bit set to TRUE overrides it.
+ * if (2) is NULL, this bit is inconsequential.
+ *
+ * (5) icon precedence bit. see previous definition.
