322 | How RDoc generates output depends on the output formatter being

323 | used, and on the options you give.
|

324 |
|
---|
325 | - HTML output is normally produced into a number of separate files
|
---|
326 | (one per class, module, and file, along with various indices).
|
---|
327 | These files will appear in the directory given by the --op
|
---|
328 | option (doc/ by default).
|
---|
329 |
|
---|
330 | - XML output by default is written to standard output. If a
|
---|
331 | --opname option is given, the output will instead be written
|
---|
332 | to a file with that name in the output directory.
|
---|
333 |
|
---|
334 | - .chm files (Windows help files) are written in the --op directory.
|
---|
335 | If an --opname parameter is present, that name is used, otherwise
|
---|
336 | the file will be called rdoc.chm.
|
---|
337 |
|

338 | For information on other RDoc options, use "rdoc --help".
