Hi everyone,

I'm new to Guix and I'm enjoying it very much so far. Here is my little
contribution: a lightweight CAD package. I don't have a lot of experience
with SolveSpace, so I haven't done any testing other than checking if
export to DXF works and drawing some sketches.

I think I've managed to follow the steps in the Submitting Patches
<https://guix.gnu.org/manual/devel/en/html_node/Submitting-Patches.html>
guide. The package has a couple of TODO's though, mostly regarding
extracting dependencies instead of building the git submodules in-place:

- mimalloc This just points to Microsoft's upstream
<https://github.com/microsoft/mimalloc/tree/f819dbb4e4813fab464aee16770f39f11476bfea>,
very close to version 2.0.6. The only other use of mimalloc I found was
rust-mimalloc, but it seems to be
<https://github.com/purpleprotocol/mimalloc_rust/tree/v0.1.20/libmimalloc-sys/c_src>
on version mimalloc 1.6.4.

- dxfrw: I believe this is an independent fork
<https://github.com/solvespace/libdxfrw>, which is unlikely useful
elsewhere.

Please consider this for inclusion,
Thank you.
K.

Hey,

In future, if you need to resend a patchset, you can use the -v flag of git
(format-patch|send-email) to indicate the revision number of the patchset,
eg:

  git send-email -3 --to=XXXXX@debbugs.gnu.org -v2
