+  RT-Manuscript_initialize.html
+
+  Sits in a Manuscript directory. Opening or reloading it from disk records
+  that directory in the browser as the RT-Manuscript library for local
+  documents. The last initializer opened or reloaded wins, so with several
+  installs open in tabs, reloading a tab selects its install.
+
+  The record is one localStorage key, shared by all file:// pages in Chrome:
+    RT.dirpr_library   the URL of this directory, without a trailing slash
+
+  Documents read it in their header block and fall back to the server when
+  it is absent.
+
+  This page does not use RT-Manuscript, so it works when the library is broken.
