6f9a9c81f6Even in the Build system. This allows grepping to make sure that there are none left un-converted: git grep "writeFile" |grep -v F\\.| grep -v doc/|grep -v writeFileString | grep -v writeFileProtected |grep -v Utility/FileIO git grep "readFile" |grep -v F\\.| grep -v doc/|grep -v readFileString |grep -v Utility/FileIO git grep "appendFile" |grep -v F\\.| grep -v doc/|grep -v appendFileString |grep -v Utility/FileIO Might be nice to automate that to prevent future mistakes...
