Subject: [PATCH v2 6/6] gnu: Add hydrus-network.

From: Tomasz Jeneralczyk <[email-masked]>
Date: Sun, 14 Aug 2022 14:46:23 +0200

Hydrus-network has a weekly release cycle and is meant to be used from its own
directory so I artificially spread it out to comply with guix's expectations.

I was not able to build the program's help files. Fixing it would probably
mean packaging a whole new build system for guix - more info in source
comments.

Also adds copyright and new used modules.

* gnu/packages/image-viewers.scm (hydrus-network): Add variable.
