+9. Dynamic loading					*tcl-dynamic*
+
+On MS-Windows the Tcl library can be loaded dynamically.  The |:version|
+output then includes |+tcl/dyn|.
+
+This means that Vim will search for the Tcl DLL file only when needed.  When
+you don't use the Tcl interface you don't need it, thus you can use Vim
+without this DLL file.
+
+To use the Tcl interface the Tcl DLL must be in your search path.  In a
+console window type "path" to see what directories are used.
+
+The name of the DLL must match the Tcl version Vim was compiled with.
+Currently the name is "tcl83.dll".  That is for Tcl 8.3.  To know for sure
+edit "gvim.exe" and search for "tcl\d*.dll\c".
