[PATCH] gnu: Add higan.

From: Taylan Ulrich Bayırlı/Kammer
Subject: [PATCH] gnu: Add higan.
Date: Sat, 04 Jun 2016 02:44:40 +0300
User-agent: Gnus/5.13 (Gnus v5.13) Emacs/24.5 (gnu/linux)

Some things to note about this package & questions:

- There's no official VCS repo and the author doesn't want automated
  tools to download files from his homepage; there's an unofficial git
  repo at GitLab but I found it unsuitable so I'm hosting the sources
  specifically for Guix at GitHub now:

  Is this OK, or is there a place we can upload the original source
  bundle for Guix to download from?

- I forgot if there's a guideline for this: the release versions are
  called 'v097', 'v098' etc. with always a 'v' in front.  Should that
  'v' appear in the version field of the package or should it be

- As seems to be tradition among emulator developers, the build system
  and the program's handling of the file system are a big pile of poo,

  * Is it principally OK to reuse the standard `build' and `install'
    phase procedures a second time, just with the CWD changed, as I do

  * The program insists on looking in ~/.local/share for some data files
    that are actually installed in $prefix/share; does my strategy here
    look OK, in that I wrap the executable to copy the data files into
    ~/.local/share every time the program is run?

Thank you!
