 """Generate java source files from protobuf files.
 
-Usage:
-    protoc_java.py {protoc} {proto_path} {java_out} {stamp_file} {proto_files}
-
 This is a helper file for the genproto_java action in protoc_java.gypi.
 
 It performs the following steps:
 1. Deletes all old sources (ensures deleted classes are not part of new jars).
 2. Creates source directory.
-3. Generates Java files using protoc.
+3. Generates Java files using protoc (output into either --java-out-dir or
+   --srcjar).
 4. Creates a new stamp file.
