Version : 3.0.12
Author(s) : Joshua Barnes, Piet Hut, and Peter Teuben
(nemo@astro.umd.edu)
License : GPL
Website :

Disk space required for installation is 67.68 Mb
After the package is installed it can be accessed using the command
/opt/lfa/startnemo
A shortcut will be installed in the KDE/GNOME desktop menu system,
as an entry in the Astronomy submenu
Summary
These are the tasks currently available under to run under NEMO. They
are a collection of program to do N-body calculations and some simple
2/3-D image processing, connected with the
N-body calculations. If program names are preceded by a dash (-)
they do not have NEMO's user interface and are sometimes not even found
in NEMO's bin area on disk (usually referred to
as $NEMOBIN). Program names ending on a star (*) are available
under this and sometimes more wildcard names (e.g. snapplot and
snapplot_ps) Program names ending in a questionmark
(?) are not available yet, but we're thinking of making them. Check
the futureplan software(8NEMO) document to see if anyone is working on
them yet.
