# Consecutively number a series of defines, for example sc/inc/globstr.hrc
# Duplicated values are renumbered but preserved, i.e. for ...START and ...END
# definitions, and commented with "XXX was duplicate".
# To insert and renumber use a higher value for the inserted definition than
# any other used, for example 9999.
# WARNING: this does not expect other defines in between and would mess around
# with them.
