# Apply KF5 coding style to all c, cpp and header files in and below the current directory

# The coding style is defined in http://techbase.kde.org/Policies/Kdelibs_Coding_Style
#
# Requirements:
# - installed uncrustify >= 0.63
#          Do not use an older version, it will lead to bad reformatting.
# - $QT_NORMALIZE_TOOL pointing to qtrepotools/util/normalize/normalize (after compiling it)
