*
* This class takes in treebank files and parses the the PTB-style format and populates a the CAS
* with constituent trees and then writes out XMI files. The CAS will contain the raw treebank data
* in a view You may find it useful to view the generated XMI files in the CAS Visual Debugger.
*
* If you do not have access to PennTreebank data or any other treebank data, then you can run this
* script with the following arguments:
*
*
-td src/main/resources/data/pos/treebank
*
-o src/main/resources/data/pos/treebank
*
-suf tree
*
*
* To view the resulting xmi file in the CAS Visual Debugger you can run the eclipse launch
* configuration labeled "CVD (cleartk-examples)". When the CVD opens select Menu -> File -> Read
* XMI CAS File. Now navigate to the single xmi file located in
* src/main/resources/data/pos/treebank. Once the file is open in the CVD be sure to examine the
* different views by selecting different values from the drop down box labeled "Select View" near
* the top of the window.
