add coverage instrumentation to existing classes

          &dhpackage;

          --basedir dir
          --datafile file
          --destination dir
          --ignore regex
          classes
          ...

## DESCRIPTION

`&dhpackage;` inserts instrumentation instructions directly into your compiled Java classes. When these instructions are encountered by the Java Virtual Machine, the inserted code increments various counters so that it is possible to tell which instructions have been encountered and which have not.

## OPTIONS

Classes may be specified individually, or as a directory tree containing multiple classes.

`--basedir dir`

- Specify the base directory containing the classes you want to instrument. This command line parameter should appear before any classes. If you are instrumenting classes in different directories, you should specify multiple basedirs.

`--datafile file`

- Specify the name of the file to use for storing the metadata about your classes. This is a single file containing serialized Java classes. It contains information about the names of classes in your project, their method names, line numbers, etc. It will be updated as your tests are run, and will be referenced by the Cobertura reporting command. Default value: "./cobertura.ser".

`--destination dir`

- Specify the output directory for the instrumented classes. If no destination directory is specified, then the uninstrumented classes will be overwritten with their instrumented counterparts.

`--ignore regex`

- Specify a regular expression to filter out certain lines of your source code. This is useful for ignoring logging statements, for example. You can have as many <ignore/> statements as you want. By default no files are ignored.

`--auxClasspath`

- Add any classes/jars that cobertura is unable to find during instrumentation.
