[Gnumed-devel] why _ and - ?

[syan tan]

Why are some of the functions named with a _ before them?

The groups users created e.g. gm-doctors and test-doc have to be quoted  
when trying to
alter drop or create them.

e.g.in psql,   drop group "gm-doctors" , instead of what the 
auto-complete seems to tell you ( drop group gm-doctors).
