 *
 * From the document of TDS:
 *
 * `Converter'
 *      Use these gadgets to select the converter program for the
 *      compiler/assembler. The purpose of the converter is to translate
 *      the error messages coming from the compiler/assembler into a format
 *      readable by the editor. The list gadget displays all converters
 *      which are available in the directory `TDS:converters'. If you want
 *      to use a compiler which doesn't have a converter, you can easily
 *      write your own one. All the converter has to do is to read from
 *      standard input the output of the compiler and to write to standard
 *      output the error messages with the following format:
 *
 *           MyConverter <compiler_error_file >ted_error_file source_file
 *
 *           `<test.c> 10 E <Error Message>' for an error
 *           `<test.c> 21 W <Error Message>' for a warning
 *
 *           where
 *           <test.c>        : source file
 *           10              : line
 *           E or W          : error or warning
 *           <Error Message> : error message
 *
 *      The converter program also receives the name of the source file as
 *      the first argument on the command line which sometimes is very
 *      helpful if the compiler didn't write the name of the source file
 *      when outputing the error messages.
