Hello,

Thank you for your feedback.

@Ludo:  The fonts I removed are copyright Bigelow & Holmes.  They are
licensed in a way that forbids them from being modified and distributed
except as part of Inferno (or software derived from Inferno) [1].

>> thing to do.  As for trademarks, please see

@Ludo:  Judging from the link there seems to be no problem with the
trademarks after all.  The bundled fonts (the ones I did not remove),
however, are provided in a format native to Inferno (and Plan 9) and can
not be rebuilt from source, which might be a problem according to this
[2] thread.

>> Could you also check whether all the code is GPLv2+ like the ‘license’
>> field suggests?

@Ludo:  According to the NOTICE files scattered through the source tree
and the Inferno home page [3] different parts of Inferno are licensed
under GPLv2+, LGPLv2+, Expat (MIT-template), Lucent Public License 1.02
and Freetype.
Am I right to assume that I have to mention all of them in the ‘license’
field even though the NOTICE in the root of the source tree [4] says
that the "collection" is governed by the GPLv2+?  
I could not find the Lucent Public License [5] in the (guix licenses)
module.  Should I add it or should I use ‘non-copyleft’?

>> Do I get it right that the build result is a script that launches

@Ludo: That is right.  I got the script from here [6].  It starts the
window manager and logs in as the current user; it is supposed to
provide a convenient entry point to start exploring the system.
Alongside this script in %out/bin/ there is also a symlink to the emu
binary which is installed by ‘mk install’ under
%out/usr/inferno/Linux/386/bin/ (Linux/arm/bin on arm machines).  This
directory contains several other executables.  I am considering making
some of them (like the Limbo compiler) available under %out/bin in the
same way as emu.

@Ludo:  My first attempt at writing the package definition used
‘gnu-build-system’. I switched to ‘trivial-build-system’ when I realised
that most phases in %standard-phases were ill suited for building
inferno.  I will try to rewrite the definition using ‘gnu-build-system’.

@Ludo:  This is Plan 9's mk (their version of make), which, I believe,
can run on POSIX systems.  Though, if we were to add mk to Guix, i would
rather package the one provided by Plan 9 from Userspace [7] since that
project seems to be more active than Inferno.

@Nils:  Your mk package seems to be unrelated to Plan 9's mk.
