Hi Ludo, Maxim,


Thanks for the review and encouragement. Sorry for the delay. I've been
in the process of relocating/starting a new job and haven't been able
to catch up on Guix stuff I have pending.

I spoke with wangp regading Lynx as an optional dependency:

> Like Sarah suggested, I’d recommend using ‘substitute*’ to
replace, say, /usr/bin/sendmail by /gnu/store/…/bin/sendmail.

I can patch sendmail and the others mentioned by Sarah. What should we
do about lynx given wangp's insight on lynx as default in bower?

all best,

jgart
