| 6 | This is multi-line data, executed line by line in their list orders. The |
||
| 7 | restrictions only affect resource modules, but not administration modules. |
||
| 8 | Lines starting with a `<tt>#</tt>' are comments. |
||
| 9 | <p> |
||
| 10 | Each line is of the format <tt>[access conditions]:[host conditions]</tt>. |
||
| 11 | <p> |
||
| 228 | reyssat | 12 | The access conditions is a list of words, which will be ANDed. The available |
| 13 | words are listed in the following table. Each word can be prefixed with |
||
| 4091 | bpr | 14 | <tt class="wims_code_words">non</tt> to reverse its logical meaning. |

| 28 | The host conditions can be any host definition, eventually plus time |
||
| 29 | definition as for any worksheets. If the first character of the host |
||
| 4091 | bpr | 30 | conditions is <tt class="wims_code_words">!</tt>, then the host/time meeting the conditions will |
| 20 | reyssat | 31 | be refused access (for the resources meeting the access conditions). |
| 32 | Otherwise they will be granted access, and subsequent lines in the |
||
| 33 | restriction definition will be ignored for those meeting the conditions. |
