Re: GNU rm's man page doesn't name chattr as a "See Also" program

[Alfred M. Szmidt]

   A defect in the 'man' reference manual document of the 'rm' program,
   is that it does not name the 'chattr' program.

Why should it even name chattr?  chattr differs from file-system to
file-system.

   Each GNU manual document fails to name other GNU reference documents.

chattr is not a GNU program.

   files that are larger than the filesystem but good enough for the GNU
   fsck program. 

There is no such program by that name.
