-/**
- * An ant task for protoc.
- *
- * Attributes specific to protoc:
- *
- * translator - The pathname of the translator (default: "protoc").
- * protocpath - The value for the --proto_path translator option.
- * outputdir - The value for the --java_out translator option.
- * dependencyfile - The file in which dependencies are stored (default: ".pbdepend").
- *
- * Example:
- *
- * <project ...>
- * <taskdef name="protoc" classname="ProtocTask" />
- * <property name="protoc.dir" value="../include/protoc"/>
- * <target name="generate">
- * <mkdir dir="tags" />
- * <protoc tagdir="tags" outputdir="out">
- * <fileset dir="${protoc.dir}">
- * <include name="*.ice" />
- * </fileset>
- * </protoc>
- * </target>
- * </project>
- *
- * The <taskdef> element installs the protoctask task.
