Hammer documentation

[Matthew Dillon]

:Maybe I was not clear before. This is not possible, since our hammer 
:utility is named 'hammer' too and therefore hammer(8) already occupies 
:the 'man hammer' slot.
:
:We can't really do anything about this anymore, unless you agree to 
:rename the utility to something else.
:
:I will, however, add a pointer to the file system intro at the start of 
:the hammer(8) manpage so that people know about hammer(5) too.
:
:Sascha

    Oh right.  Ach. ok, I guess having the pointers will work.
