EDIT
14 SeptemberUpdated: now include a newer version of the Help and of GMIC
A peculiarity of this version is that can be started in 2 very different mode as were 2 different versions of gimp

1) A barebone, or basic or as i called "No_Extra" version.
That may look similar to that from the Gimp for Windows builds the difference is that here the help manual, python Support, support to open digital photo files is included out of the box
In this configuration load much faster
2) or as Gimp_PhotoComix_Lab that integrate the best plugin script and addon for Photo( all types of photo editing ) and "Comix", the word is used here in a broader sense to indicate digital sketching, painting and graphic
