  Priority:  low     |    Milestone:         
 Component:  Cabal   |      Version:  1.2.2.0
  Severity:  normal  |     Keywords:         
Difficulty:  normal  |   Ghcversion:  6.4.2  
  Platform:  Linux   |  
---------------------+------------------------------------------------------
 There are a few packages around which declare
 {{{
 license-file: LICENSE
 }}}

 but then that LICENSE file actually does not exist. Currently we do not
 discover this until we try and install at which point we get the unhelpful
 error:
 {{{
 setup: LICENCE: copyFile: does not exist (No such file or directory)
 }}}

 It would be much more helpful to users and developers alike if we warned
 in the configure step if the file was missing.

 This is partly a transitional issue, since older versions of Cabal did not
 install license files at all, so it never noticed.
