I recently switched to all-Python :-). Yet, incomplete notes still
remain incomplete.
By the way, in Python, is .split(',') the only way to seprate
multiple (input) identities in a list/dictionary? Shouldn't the parser,
with the option "multiple: yes" do this already for the scripter?
For example, in
#%option
#% key: msx
#% type: string
#% gisprompt: old,double,raster
#% description: Low resolution multi-spectral image(s)
#% required: yes
#% multiple: yes
#%end
it would be nice to have a new list after
newlist = options['msx']
Or would this cause trouble?
Thank you,
Nikos
