These are created at build time 1.13 +by the harfbuzz build system; but as we don't use that build system in mozilla, 1.14 +it is necessary to refresh these files when updating harfbuzz, and check them in 1.15 +to the mozilla tree. (This avoids adding the ragel processor to mozilla's build 1.16 +prerequisites.) 1.17 + 1.18 +The normal approach to updating harfbuzz, therefore, is to pull the latest HB 1.19 +source into a scratch directory and do a local build; then copy the original 1.20 +sources AND the generated headers mentioned above from the build directory into 1.21 +the mozilla tree. 1.22 + 1.23 +In addition, the src/Makefile.in file here is NOT from upstream, nor is it 1.24 +generated from src/Makefile.am (the original harfbuzz version); it is a mozilla- 1.25 +specific makefile that is maintained by hand. It should only need updating when 1.26 +new source files or exported headers are added in harfbuzz.
