-/**
- * An abstract ant task for slice translators. The task minimizes
- * regeneration by checking the dependencies between slice files.
- *
- * Attributes:
- *
- * dependencyfile - The file in which dependencies are stored (default: ".depend").
- * outputdir - The value for the --output-dir translator option.
- * casesensitive - Enables the --case-sensitive translator option.
- * ice - Enables the --ice translator option.
- *
- * Nested elements:
- *
- * includepath - The directories in which to search for Slice files.
- * These are converted into -I directives for the translator.
- * define - Defines a preprocessor symbol. The "name" attribute
- * specifies the symbol name, and the optional "value" attribute
- * specifies the symbol's value.
- * fileset - The set of Slice files which contain relevent types.
- *
