| * This class acts as both the ITeamNature and the ITeamProvider instances |

| * |
| * The current stat of this class and it's plugin is EXPERIMENTAL. |
| * As such, it is subject to change except in it's conformance to the |
| * TEAM API which it implements. |
| * |
| * Questions: |
| * |
| * How should a project/reource rename/move effect the provider? |
| * |
| * Currently we always update with -P. Is this OK? |
| * - A way to allow customizable options would be nice |
| * |
| * Is the -l option valid for commit and does it work properly for update and commit? |
| * |
| * Do we need an IUserInteractionProvider in the CVS core |
| * - prompt for user info (caching could be separate) |
| * - get release comments |
| * - prompt for overwrite of unmanaged files |
| * |
| * Need a mechanism for communicating meta-information (provided by Team?) |
| * |
| * Should pass null when there are no options for a cvs command |
| * |
| * We currently write the files to disk and do a refreshLocal to |
| * have them appear in Eclipse. This may be changed in the future. |
