| <p>This package is a somewhat simplistic environment checking |
| utility. It allows users in various environments to self-test |
| their specific deployed environment to ensure that they have the |
| correct classes present. Which is currently focused on various |
| XML issues but is architected to be generic and easily extensible.</p> |
| <p>Most of the documentation is included in the Javadocs for the |
| various classes. Which is a framework into which various 'checkers' |
| or WhichProject implementations can be plugged; it then asks each |
| implementation to fill in whatever information it can into a common |
| Hashtable, which it then reports back to the user in one of a number |
| of formats.</p> |
| <p>Most useful for reporting environments in automated builds or |
| for a self-help system version detection for users reporting bugs.</p> |
