NNCP should run on any POSIX-compatible operating system with file
systems supporting directory and filename's length up to 57 characters.

NNCP is written on @url{https://golang.org/, Go} programming language
and you have to install Go compiler (1.7+ version is highly
recommended). @emph{Make} (BSD and GNU ones are fine) is recommended for
convenient building. @url{https://www.gnu.org/software/texinfo/,
Texinfo} is used for building documentation.

Included required libraries:

Get @ref{Tarballs, the tarball}, check its
@ref{Integrity, integrity and authenticity} and run @command{make}.
@emph{nncp-*} binaries will be built in the current directory:

@verbatim
% wget http://www.nncpgo.org/download/nncp-0.1.tar.xz
% wget http://www.nncpgo.org/download/nncp-0.1.tar.xz.sig
% gpg --verify nncp-0.1.tar.xz.sig nncp-0.1.tar.xz
% tar xf nncp-0.1.tar.xz
% make -C nncp-0.1 all
@end verbatim

There is @code{install} target respecting @env{DESTDIR}. It will
install binaries and info-documentation.
