Well now ...

There's a lot to know before a .desktop file will pass
`/usr/bin/desktop-file-validate`
I ended up spending more time than I had to spend here:

   https://www.freedesktop.org/wiki/Specifications/menu-spec/

and the specific info about Desktop Categories is here:

   https://specifications.freedesktop.org/menu-spec/latest/apa.html

I ended up with the if-block below my sig ...

Note that the monteverdi app ends up all by itself under the 'Science and
Math'
Desktop Menu Category.

But now the package passes sbopkglint without Errors, Warnings or Hints.

Thanks for the feedback Dave and B. Watson !

Question:  is there a better way ( or a recommended way ) to enter long,
formatted
lists of text like NEW_CAT in the code snippet below ?

Note that many other SBo Packages also fail `desktop-file-validate` so
maybe this was
all a fools-errand :)

# ------------------- cut  here -----------------
# default Categories=Education;Science;ImageProcessing;Geography;Qt;
# in build/monteverdi.desktop annoys sbopkglint try this instead ...
# see: https://specifications.freedesktop.org/menu-spec/latest/apa.html

if [ "$MONTEVERDI" = "ON" ] ; then
   NEW_CAT="Science;Math;ImageProcessing;DataVisualization"
   NEW_CAT="$NEW_CAT;Geoscience;NumericalAnalysis;Qt;"

   sed -i -e "s/^Categories=.*$/Categories=$NEW_CAT/" \
   $PKG/usr/share/applications/monteverdi.desktop
fi
