Information on how to get groff and related information is
available at the groff page of the GNU website
⟨http://www.gnu.org/software/groff⟩.
Three groff mailing lists are available:
bug tracker activity (read-only) ⟨bug-groff@gnu.org⟩;
general discussion ⟨groff@gnu.org⟩; and
commit activity (read-only) ⟨groff-commit@gnu.org⟩, which
reports changes to groff's source code repository by its
developers.
Details on repository access and much more can be found in the
file README at the top directory of the groff source package.
A free implementation of the grap preprocessor, written by Ted
Faber ⟨faber@lunabase.org⟩, can be found at the grap website
⟨http://www.lunabase.org/~faber/Vault/software/grap/⟩. This is
the only grap supported by groff.
