[Gnumed-devel] check-prerequisites.py and also the directory external-tools

[Jim Busser]

In addition to updating this script to check also for texlive (or one of its 
installed binaries, pdflatex), should the script also be adjusted to henceforth 
also check if it can see in the system PATH

        gm-print_doc

With regard to external-tools, if it contains some things unessential to the 
running of gnumed, but also things that would henceforth be considered 
essential  as soon as the user would attempt to invoke a built-in GNUmed button 
(for example if we would now consider gm-print_doc to be essential) might it 
make sense to rename the current

        external-tools 

into

        external-tools-optional

and to create another

        external-tools-needed (or -base or -default)

to somehow indicate their essential nature.

Lastly, the experience with gm-print_doc made me wonder whether we would wish 
anything like

        check-prerequsites.py

to be accessible from a GNUemed client Help menu. On account of it being a .py 
file and not an .sh file, double-clicking in the GUI does not chain to 
auto-invoke the .py file but instead the user is given an application list 
which does not include Python. The case is different from (for example) 
gm-from-cvs.sh which, if double-clicked, offers the user a dialog whether to
        Run in Terminal, Display, Cancel or Run
