currently that's how it is,

nope, everything(?) in the bin/ dir gets run at build time.

desktop-conf/welcome_message.sh can take care of that for you, as it is
run at window manager login-time.

for welcome message I think it would be rather easy. For the main docs,
nothing is impossible but it gets a bit harder. Probably the best we can
do is edit the desktop road-sign help icon (~/Desktop/help.desktop or
something like that) to point to the LANG code version. Changing the
help button in the Geospatial menu is a bit more difficult (needs sudo;
see opencpn data license agreement script for that) as is the web browser
homepage (see bin/install main docs(?) for a way of trying to do that).

For now I think editing the target of the welcome_message.txt and ~/Desktop/
help icon from welcome_message.sh is the most effort effective thing to do.
Yes another job for `sed -i -e 's|from|to|'` ...

I think the doc layout is still a bit messy as we figure it all out, but
the script logic is now fairly sane once you get your head around it,
so don't worry you'll figure it out soon.
