Hello Guix!

When someone=E2=80=99s working on a channel, it=E2=80=99s typical to have t=
hat channel
already in your =E2=80=98guix=E2=80=99 and to use =E2=80=98guix build -L /p=
ath/to/checkout PKG=E2=80=99
to test a package from a working copy of the channel.  Here=E2=80=99s what =
it
looks like:
