In the third form, a list of supported features is sent |
| 47 |
+ |
to the standard output, one per line. |
| 48 |
+ |
If additional arguments follow, they are checked for presence in |
| 49 |
+ |
this list. |
| 50 |

If a feature includes subfeatures, these may be checked as well by |
| 51 |
+ |
specifying: |
| 52 |
+ |
.nf |

|
| 54 |

rpict -features FeatName=subfeat1,subfeat2 |
| 55 |

.fi |
| 57 |
+ |
If any named feature or subfeature is missing, an error is |
| 58 |
+ |
reported and the program returns an error status. |
| 59 |
+ |
If all of the named features are present, a zero status is returned. |

Most options are followed by one or more arguments, which must be |
| 62 |
|
separated from the option and each other by white space. |
