+The @file{@var{datadir}/texinfo/ext/} directory contains the
+init files directly loaded from @command{texi2any} code.  When loaded from
+@command{texi2any} code directly, init files are only searched for
+in that directory, being considered as part of the program and not as user
+customization.  Since the directory is also in the list of directories searched
+for init files loaded by the @option{--init-file} option, those init
+files can also be loaded as regular user specified init files.

 Additional directories may be prepended to the list with the
 @option{--conf-dir} option (@pxref{Invoking @command{texi2any},,, texinfo, 
Texinfo}).
