Converting python plugin-in shellout.py from gimp 2.x to 3.x

[Neptunus]

Hi iiey,

I followed your instructions to install nikplugin :

• I created a folder named nikplugin\ under C:\Program Files\GIMP 3\lib\gimp\3.0\plug-ins\
  
• I copied nikplugin.py in this folder.
  
• The Nik collection is in C:\Program Files\Google\Nik Collection\ so, I didn’t change anything in the nikplugin.py file.
  
• I re-started GIMP 3, opened a picture and tried to find NikCollection among the filters without any success.
  

Please, could you help me ?
Note that ShellOut plugin worked well with Gimp 2.

Thanks.
