# A treeprocessor that increments each level-1 section number by the value of
# the `sectnumoffset` attribute.
#
# In addition, if `subsectnumoffset` is defined and greater than zero,
# the numbers of subsections in the first section encountered will
# be incremented by the offset.
#
# The numbers of all subsections will be
# incremented automatically since those values are calculated dynamically.
#
# Run using:
#
# asciidoctor -r ./lib/sectnumoffset-treeprocessor.rb -a sectnums -a sectnumoffset=1 lib/sectnumoffset-treeprocessor/sample.adoc
