  # find data/ sources/ specifications/ documents/ licenses/ install.sh -type f -exec sed -i -e 's|0\.7\.3|0.7.4|g' -e 's|^version_micro 3|version_micro 4|g' '{}' ';'
  # find sources/ -name *.h -exec sed -i -e 's|_program_version_micro_s F_string_ascii_3_s|_program_version_micro_s F_string_ascii_4_s|g' -e 's|_program_version_micro_s_length F_string_ascii_3_s_length|_program_version_micro_s_length F_string_ascii_4_s_length|g' '{}' ';'
  # sed -i -e 's|version_micro 3|version_micro 4|g' data/build/settings* data/build/stand_alone/settings.*
