+Funcmap files are loaded from external libs. External lib paths
+are configured in the conf node plugins/funcmap/search_paths, which
+has the same syntax as the symbol library.
+<p>
+Once a funcmap is referenced (from the <i>funcmap</i> attribute of
+a component, typically coming from the <i>funcmap</i> attribute of a
+symbol), the plugin loads the file from the external lib and places it
+in the sheet local library. This keeps sheets self-contained and portable,
+not relying on external files.
+<p>
+Both the sheet local library and the external library can be browsed
+using the funcmap library dialog. The sheet local library can be
+flushed (removed) from the File/Maintenance menu; upon the next compiation
+all funcmap references are imported into the sheet local library from the
+external libraries again. This is how external library changes can be
+applied to a sheet.
