+# Per-device configuration is kept here in dotfiles.git too, but it won't be
+# activated just by linking .zshrc. You also need to link ~/.device_pre and
+# ~/.device_post to the relevant per-device files under `device`.
+
+# All exports in pre-config are prefixed with `DEVICE_`, and are used to toggle
+# features or identify installations in .zshrc or other scripts which are part
+# of dotfiles.git.
+
+device_preconfig() {
+  source ~/.device_pre
+}
+
+# The post-config file is intended to run commands that are so specialized to
+# the relevant device that it wouldn't make sense to include as a toggleable
+# feature in the main .zshrc.
