+<!-- library location test
+
+Checks the header block that locates the RT-Manuscript library, and the
+initializer that records it.
+
+  stored  = localStorage "RT.dirpr_library", written by RT-Style Manuscript setup.html
+  server  = https://style.ReasoningTechnology.com/Manuscript
+  used    = RT.dirpr_library after the header block
+
+Automatic checks, made while the page parses:
+
+  1. used == stored, or used == server when nothing is stored
+  2. the engine ran: RT.load and RT.Module exist
+  3. every engine script on the page came from used, so no install is mixed with another
+
+Manual procedure, with two installs A and B (for example the authored
+Manuscript.copy and consumer/Manuscript):
+
+  open A's initializer, reload this page   -> used == A, checks pass
+  open B's initializer, reload this page   -> used == B, checks pass
+  reload A's initializer tab, reload this  -> used == A
+  Uninstall in either initializer, reload  -> used == server
+  record a directory that does not exist   -> page does not format; the plain
+                                              text report still shows used
+
+The report is written as plain text during parsing, so it can be read when
+the engine fails to load.
