# This script produces the file "menu_call_stats_list.c" containing
# pointers to the call statistics for all menu items in the core RockBox.
# Files with menu items that should get into this list must be compiled
# so that all the temporary files are kept (in particular, the result of
# the preprocessing). Usually this is done by including '-save-temps' into
# the list of the compiler options. In that case, the preprocessed files
# have the extension '.i' and are stored in the same directory as the
# original '.c' files.
