 gfx/harfbuzz status as of 2012-08-16:

 This directory contains the "harfbuzz-ng" source from the 'master' branch of

 git://anongit.freedesktop.org/git/harfbuzz.

 UPDATING:

 Note that hb-ot-shape-complex-indic-machine.hh and gfx/harfbuzz/src/hb-version.h

 are not present in the upstream Git repository. These are created at build time

 by the harfbuzz build system; but as we don't use that build system in mozilla,

 it is necessary to refresh these files when updating harfbuzz, and check them in

 to the mozilla tree. (This avoids adding the ragel processor to mozilla's build

 prerequisites.)

 The normal approach to updating harfbuzz, therefore, is to pull the latest HB

 source into a scratch directory and do a local build; then copy the original

 sources AND the generated headers mentioned above from the build directory into

 the mozilla tree.

 In addition, the src/Makefile.in file here is NOT from upstream, nor is it

 generated from src/Makefile.am (the original harfbuzz version); it is a mozilla-

 specific makefile that is maintained by hand. It should only need updating when

 new source files or exported headers are added in harfbuzz.
