Hi,
And here I go again. This time it's a whole new program, that will
allow you to change the st_author field on GNU/Hurd.
As I haven't received any comments on the last patch for fileutils, I will
assume that it is OK. :)
The only thing that is left I think is for chmod/chown to be able to change
the permissions of the underlying node and for ls to be able to list those
permissions.. Unless someone has more ideas for fileutils.
2002-04-10 Alfred M. Szmidt <[EMAIL PROTECTED]>
* src/chauthor.c: New file.
* src/Makefile.am: Add rules for chauthor.
* configure.ac: Check for hurd.h.
