- 
- 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 header mentioned above from the build directory into
- the mozilla tree.
- 
- If the collection of source files changes, manual updates to moz.build may be
- needed, as we don't use the upstream makefiles.
-+
-+The in-tree copy may be omitted during build by --with-system-harfbuzz.
-+Make sure to keep pkg-config version check within old-configure.in in sync
-+with checkout version or increment latest tag by one if it's not based
-+on upstream release.
