1 Please use ./import_expat.sh to update. For example to import from a tar and rebuild: 2 3 (croot && cd external/expat && ./import_expat.sh ~/Downloads/expat-2.1.0.tar.gz && mm -j32 -B) 4 5 When updating to new versions, please remove any unnecessary build 6 files to make the diff of what we are using clearer. It is reasonable 7 to keep new docs, examples, and tests for reference. 8
