Thank you for expressing some confidence in this particular repository. 
  I have downloaded and installed darktable, both X86_64 with OpenCL 
addons (as the X86_64 machine has an Nvidia tesla board) and the IA-32 
version on my laptop.  If I need genuine Nikon software or Photoshop et 
al., I must invoke MS Windows 7 under VirtualBox, a cumbersome solution; 
thus, I prefer a native Linux application.  At present, in addition to 
gimp (and addons thereto), I used Corel AfterShot Pro (the replacement 
for Bibble Pro after Corel bought the product/company -- in the USA, it 
has been declared that corporations are people -- so why cannot any of 
us in the USA buy another person -- sigh).  The comments on the 
limitations of Darktable posted in this thread seem to be true; however, 
the final product it produces is useful for some purposes.  Eventually, 
someone will have the full functionalities of the various "standard" 
proprietary applications that only are available for MS Windows or Mac 
OS X implemented in an application for Linux.  It appears that Gimp plus 
plugins/addons comes closest to this functionality at the moment.
