In case this will be helpfull for someone here [1] is my Docker

file for building GHC-7.10.3 on Debian Wheezy from sources, also

here is the image itself [2].  Note, Docker Hub shows that image

size is 1Gb, however running `docker images` locally shows me

6.354 GB.  I tried to make some cleanup but my docker skills are

quite weak, so I will be happy if anyone can teach me how to

reduce image size.

Regards!
