Hey GWL-hackers,

Congratulations on the 0.2.0 release! After re-reading the info manual,
but not understanding all parts, I keep running into the problem of not
actually being totally sure on how to do some fairly basic things.

How do I install GWL, while using a `guix pull'-managed guix (so with
guile3.0)? As the `guix' that is a propagated input still uses guile2.2,
this is not as simple as I had hoped it would be.

Currently, I have the following wrapper in $HOME/.local/bin/gwl:
--8<---------------cut here---------------start------------->8---
#!/usr/bin/env bash
export GUILE_LOAD_PATH=$HOME/.guix-profile/share/guile/site/2.2
export GUILE_LOAD_COMPILED_PATH=$HOME/.guix-profile/lib/guile/2.2/site-ccache:$HOME/.guix-profile/share/guile/site/2.2
$HOME/.guix-profile/bin/guix workflow "$@"
--8<---------------cut here---------------end--------------->8---

This wrapper seems to work for stuff like `gwl --help' and `gwl
--prepare=<file>'. I'd much rather prefer something less terribad though
:).

My other issue relates to actually running computations usings
GWL. Given the following workflow file:

--8<---------------cut here---------------start------------->8---
process hello-world
  # { echo "Hello, world!" }

workflow do-the-thing
  processes hello-world
--8<---------------cut here---------------end--------------->8---

I can run GWL to both prepare and graph my workflow, yet I get the
following backtrace when trying actually `gwl --run=<file>':

--8<---------------cut here---------------start------------->8---

--8<---------------cut here---------------end--------------->8---

Thanks for any guidance, and feel free to point me to the right section
of The Fine Manual that I simply misunderstood.
