+0.1.6
+
+Fixed the raco helper test for the Racket package build service: raco help
+legitimately writes usage text to stderr, while raco test --drdr treats any
+stderr output as a test failure. The test now captures child stdout/stderr.
+Changed list-dir/files so its regexp matches only the entry name returned by
+file-name-from-path, instead of the complete path.
+
 0.1.5
 
 Added raco helper for invoking Racket tools from makefile recipes.
