| variable_requires(TEST_VARIABLE RESULT_VARIABLE |
| REQUIRED_VARIABLE1 |
| REQUIRED_VARIABLE2 ...) |
| |
| The first argument (TEST_VARIABLE) is the name of the variable to be |
| tested, if that variable is false nothing else is done. If |
| TEST_VARIABLE is true, then the next argument (RESULT_VARIABLE) is a |
| variable that is set to true if all the required variables are set. |
| The rest of the arguments are variables that must be true or not set |
| to NOTFOUND to avoid an error. If any are not true, an error is |
| reported. |
