That seems strange to me. Maybe we use the subpackage tools then for the data-tools and call the current tools misc?

[Martin Lange]

Yeah, maybe. Could also have left the as away, but data is just so common and was already used in the code I guess. In other places, I called it fmdata. But then, fm.data would be similarly long.

[Sebastian Müller]

Why not use import finam as fm in the examples as single import? The other packages could follow that:

import finam_netcdf as fm_nc
import finam_plot as fm_plt
import finam_graph as fm_grf
import finam_mhm as fm_mhm
import finam_ogs as fm_ogs
import finam_formind as fm_for
