1. Create an empty text file.  The standard file extension for piper files is .piper
2. Set a reader for your pipeline.   To set values to parameters used by the reader class, simply add one or more name=value pairs after the class name.   * readFiles is a convenience command.  "readFiles my/data" is equivalent to "reader FileTreeReader InputDirectory=my/data".
3. add annotation engines and cas consumers to your pipeline. To set values to parameters used by the annotation engine class, simply add one or more name=value pairs after the class name. 
4. load common groups of components from another piper file.  See Table 2 for piper files in cTAKES.
   
5. reader, load and To add multiple pipeline components from a package not standard to cTAKES, use the package command to point to it.
   reader, load and add* commands all take class names or file directories as their first parameter.  If the class is not in a standard cTAKES module's cr ae or  or cc package package, or a piper file is not in a standard module's s pipeline/ directory then the package or path must be specified for that component / file.  Using package simplifies this
6. Use package to simplify adding multiple pipeline components from a package not standard to cTAKES.
