Hopefully it should work on all POSIX systems.
Preferable way is to download tarball with the signature from website:

@example
$ [fetch|wget] http://www.goredo.cypherpunks.ru/download/goredo-@value{VERSION}.tar.zst
$ [fetch|wget] http://www.goredo.cypherpunks.ru/download/goredo-@value{VERSION}.tar.zst.sig
$ gpg --verify goredo-@value{VERSION}.tar.zst.sig goredo-@value{VERSION}.tar.zst
$ zstd -d < goredo-@value{VERSION}.tar.zst | tar xf -
$ cd goredo-@value{VERSION}
$ GOPATH=`pwd` go build go.cypherpunks.ru/goredo
$ ./goredo -symlinks        # create redo-* commands symlinks
$ export PATH=`pwd`:$PATH   # let your system know about goredo
@end example

@include download.texi

You @strong{have to} verify downloaded tarballs integrity and
authenticity to be sure that you retrieved trusted and untampered
software. @url{https://www.gnupg.org/, GNU Privacy Guard} is used
for that purpose.

For the very first time it is necessary to get signing public key and
import it. It is provided below, but you should check alternative
resources.

@example
$ gpg --auto-key-locate dane --locate-keys goredo at cypherpunks dot ru

It is also @command{go get}-able:

@example
$ go get go.cypherpunks.ru/goredo
$ goredo -symlinks
@end example

If you have problems with @code{*.golang.org}'s inability to verify
authenticity of @code{go.cypherpunks.ru} TLS connection, then you can
disable their usage by setting @env{GOPRIVATE=go.cypherpunks.ru}. You
can override CA certificate file path with @env{SSL_CERT_FILE} and
@env{GIT_SSL_CAINFO} environment variables.

You can obtain development source code with
@command{git clone git://git.cypherpunks.ru/goredo.git}
(also you can use @url{https://git.cypherpunks.ru/goredo.git}).
