Hi,

swig is depended upon by 5206 packages. This means that any updates will
have to go through the core-updates branch. The branch has swig 4.0.1
since this December. Sorry for the duplicated effort...

You might want to send a patch to build swig with guile-3.0 instead of
the guile-2.2 used currently on core-updates. If you decide to do so,
please use [PATCH core-updates] in the subject. You can do this easily
by passing --subject-prefix="PATCH core-updates" to git format-patch.

See point 8 of `info '(guix)Submitting Patches'` for more details.

Regards,
Jakub Kądziołka

True.

No problem! :-)

Ok, will do.

Sorry, I didn't know I had to do this. Will do for all my future
core-updates patches.
