* The cvs_file structure is used to represent any file or directory within

* points back to the parent node in the directory tree structure (it is
* NULL if the directory is at the wd of the command).
*
* The <cf_cvstat> field gives the file's status with regards to the CVS
* repository. The file can be in any one of the CVS_FST_* states.
* If the file's type is DT_DIR, then the <cf_ddat> pointer will point to
* a cvs_dir structure containing data specific to the directory (such as
* the contents of the directory's CVS/Entries, CVS/Root, etc.).
