exit-hook is undocumented and is not called from a non-interactive environment |

Currently using guile version 1.8.8. I have been told that this also
affects the current upstream version as well.
My current project involves using a C library that has some
initialization and cleanup functions.
First:
The library initialization part is well-handled, but I could not find
a way to do the library cleanup part. After doing some web searches,
I found an answer in "exit-hook", except that it was not clear from
the Guile reference manual that it existed. It should probably be
documented a little more clearly.
Second:
When I write a scheme script that adds some function to exit-hook, it
is not invoked from a non-interactive call to guile. I have a file
test.scm that looks like so:
(add-hook! exit-hook (lambda () (display "bye\n")))
In an interactive environment:
$ guile -l test.scm
guile> (exit)
bye
$
In a non-interactive environment:
$ guile -s test.scm
$
Nothing is printed. As far as I can tell, exit-hook should be made
available in a non-interactive environment so that modules loading
libraries can cleanup easily.

Hi,
Closing out this bug, as it seems that the current situation shouldn't
be changed, and also that atexit sounds sufficient. Please open a new
report if you still have issues :)
Regards,
Andy
