# Copy a list of file into a destination directory. Potentially renaming
# files are they are copied. This also ensures that symlinks are followed
# during the copy (i.e. the symlinks are never copied, only their content).
#
# Variables:
#  dest: Destination directory path.
#  sources: List of source files or directories to copy to dest.
#  renaming_sources: Optional list of source file paths that will be renamed
#    during the copy operation. If provided, renaming_destinations is required.
#  renaming_destinations: Optional list of destination file paths, required
#    when renaming_sources is provided. Both lists should have the same size
#    and matching entries.
#  args: Optional. Additionnal arguments to the copy_ex.py script.
#
#  The following variables have the usual GN meaning: data, deps, inputs,
#  outputs, testonly, visibility.
