-# bash-completion file for CMake

-# We will try to complete cmake commands options

-#  [cmake|cpack|ctest] <level0> <level1> <level2>
-#
-#  level0 is top level cmake/cpack/ctest options
-#  level1 is the first argument of level0 option
-#  level2 is the seconf argument of level1 argument
-#   FIXME: I don't know how to handle level2

-# The file has been proposed for inclusion in the bash-completion package
-# https://alioth.debian.org/tracker/?func=detail&atid=413095&aid=312632&group_id=100114
-# In the meantime,
-#   1) If you want to test bash completion for cmake/cpack/ctest
-#      just source the current file at bash prompt
-#      . ./cmake-completion
