Thanks.  This turns out to get exactly what I got from the
link in the bug report (except for ".git" :-)

=>diff -r --brief metanet-master/ metanet/
Only in metanet/: .git

Once I figured out that the "." in the name represented subdirs I used
"locate" to find the spot in the SCI tree.  But since I know nothing about
Java, the problem was still opaque to me.  Thanks for the hint!
(Indeed "grep" and "find" are indeed close friends of mine.)

Ok.

I'll see if I can modify the sources to compile.  (Who will notify the
Serge, et al. that they need to mod their package to work with 5.3.0?)

But then what?  Having just started playing with the ATOMS stuff last
evening, I'm not sure where to put the result of my build so that ATOMS
can see the local module and install it.  I know about

   atomsSetConfig('offLine', 'True');

but then how do I get the ATOMS GUI to work?  Or should I just
use the commandline calls to atoms?

Do I do something like:

atomsRepositoryAdd('file://<path to the directory containing metanet>'); ?

Anyway, thanks for all your help.  I really appreciate you and Sylvestre
(and others) taking the time to steer semi-novices like me. (Novice to
scilab-5, not to Linux and package building).
