+# If a system has a package installed and that package provides a `.pc` file
+# this rule can be used to make that library visible to other rules. The `name`
+# of this rule should be the pkg-config name. For example, if
+# `pkg-config --libs gtest` prints out the flags to link against gtest, then
+# `external_pkgconfig_library(name = "gtest")` would allow other rules to
+# depend on gtest.
+#
+# WARNING: dependencies are not resolved by pkg-config, so these must be specified
+# manually with `deps`. Additionally, ABI/platform differences are not handled
+# by this rule so be careful not to cache it in Remote Execution etc to prevent
+# different machines from reusing the outputs of these rules.
