This directory contains tests for the java.io package.  Some importantthings to note:-- The file dataoutput-jdk.out is the results of the DataInputOutputTest   test run through the JDK.  It is needed for the real test so please   don't delete it.-- The directory filetest and its contents are used for the FileTest test.   If that test bombs in the middle, it may leave the directory renamed   to something else.  In that case, you will need to rename it back   manually to re-run the test after making fixes.
