7 Copying
*********

GNU ‘grep’ is licensed under the GNU GPL, which makes it “free
software”.

   The “free” in “free software” refers to liberty, not price.  As some
GNU project advocates like to point out, think of “free speech” rather
than “free beer”.  In short, you have the right (freedom) to run and
change ‘grep’ and distribute it to other people, and—if you want—charge
money for doing either.  The important restriction is that you have to
grant your recipients the same rights and impose the same restrictions.

   This general method of licensing software is sometimes called “open
source”.  The GNU project prefers the term “free software” for reasons
outlined at
<https://www.gnu.org/philosophy/open-source-misses-the-point.html>.

   This manual is free documentation in the same sense.  The
documentation license is included below.  The license for the program is
available with the source code, or at
<https://www.gnu.org/licenses/gpl.html>.
