| 598 | =head1 DESCRIPTION
|
| 599 |
|
| 600 | Parse the Linux feature files from Documentation/features (by default),
|
| 601 | optionally producing results at ReST format.
|
| 602 |
|
| 603 | It supports output data per architecture, per feature or a
|
| 604 | feature x arch matrix.
|
| 605 |
|
| 606 | When used with B<rest> command, it will use either one of the tree formats:
|
| 607 |
|
| 608 | If neither B<--arch> or B<--feature> arguments are used, it will output a
|
| 609 | matrix with features per architecture.
|
| 610 |
|
| 611 | If B<--arch> argument is used, it will output the features availability for
|
| 612 | a given architecture.
|
| 613 |
|
| 614 | If B<--feat> argument is used, it will output the content of the feature
|
| 615 | file using ReStructured Text markup.
