@cindex manual, how to read
96
To read this manual, begin at the beginning, reading from left to right
97
and top to bottom, until you get to the end. Then stop. You may pause
98
for a beer anywhere in the middle as well, if you wish. (Please note,
99
however, that The King strongly advises against heavy use of
100
prescription pharmaceuticals, based on his extensive personal and
101
professional experience.)

The GNU @code{hello} program produces a familiar, friendly greeting.
112
It allows nonprogrammers to use a classic computer science tool which
113
would otherwise be unavailable to them. Because it is protected by the
114
GNU General Public License, users are free to share and change it.

GNU @code{hello} was written by Mike Haertel, David MacKenzie, Jan
117
Brittenson, Charles Hannum, Roland McGrath, Noah Friedman, Karl
118
Eichwalder, and @w{The King}.
