+# The install names of our dynamic libraries contain a special segment token
+# that denotes where the dynamic library is located in the installation set.
+# The segment token consists of "@", optionally followed by ".", followed by 50
+# "_", followed by a location token (one of "URELIB", "OOO", "OXT", or "NONE").
+#
+# Typically, the segment token is the first segment of a relative install name.
+# But the segment token may also appear within an absolute install name. That
+# is useful when tunnelling the segment token into the external build process
+# via a --prefix configure switch, for example.
+#
+# When another dynamic library or an executable links against such a dynamic
+# library, the path recorded in the former to locate the latter is rewritten
+# according to the below %action table. The result path consists of the prefix
+# from the action table followed by the suffix of the dynamic library's install
+# name. If the special segment token does not contain the optional "." after
+# the "@", the suffix consists of all segments after the special token segment.
+# If the special token segment does contain the optional ".", then the suffix
+# consists of just the last segment of the original install name.
+#
+# That latter case is useful for libraries from external modules, where the
+# external build process locates them in some sub-directory.
