4.6.4 License Notices for Other Files

Small supporting files, short manuals (under 300 lines long) and rough documentation (README files, INSTALL files, etc) can use a simple all-permissive license like this one:

     Copying and distribution of this file, with or without modification,
     are permitted in any medium without royalty provided the copyright
     notice and this notice are preserved.

If your package distributes Autoconf macros that are intended to be used (hence distributed) by third-party packages under possibly incompatible licenses, you may also use the above all-permissive license for these macros.
