Debian Package Tracking System
|
| 299 |
------------------------------
|
| 300 |
|
| 301 |
The Package Tracking System (PTS) has the following commands:
|
| 302 |
|
| 303 |
subscribe <srcpackage> [<email>]
|
| 304 |
Subscribes <email> to all messages regarding <srcpackage>. If
|
| 305 |
<email> is not given, it subscribes the From address. If the
|
| 306 |
<srcpackage> is not a valid source package, you'll get a warning.
|
| 307 |
If it's a valid binary package, the mapping will automatically be
|
| 308 |
done for you.
|
| 309 |
|
| 310 |
unsubscribe <srcpackage> [<email>]
|
| 311 |
Unsubscribes <email> from <srcpackage>. Like the subscribe command,
|
| 312 |
it will use the From address if <email> is not given.
|
| 313 |
|
| 314 |
which [<email>]
|
| 315 |
Tells you which packages <email> is subscribed to.
|
| 316 |
|
| 317 |
keyword [<email>]
|
| 318 |
Tells you the keywords that you are accepting. Each mail sent through
|
| 319 |
the Package Tracking System is associated to a keyword and you receive
|
| 320 |
only the mails associated to keywords that you are accepting. Here is
|
| 321 |
the list of available keywords :
|
| 322 |
* bts : mails coming from the Debian Bug Tracking System
|
| 323 |
* bts-control : mails sent to control@bugs.debian.org
|
| 324 |
* buildd : failed build logs generated by build daemons
|
| 325 |
* summary : automatic summary mails about the state of a package
|
| 326 |
* upload-source : announce of a new source upload that has been installed
|
| 327 |
* upload-binary : announce of a new binary-only upload (porting)
|
| 328 |
* katie-other : other mails from ftpmasters (override disparity, etc.)
|
| 329 |
|
| 330 |
keyword <srcpackage> [<email>]
|
| 331 |
Same as previous item but for the given source package since
|
| 332 |
you may select a different set of keywords for each source package.
|
| 333 |
|
| 334 |
keyword [<email>] {+|-|=} <list of keywords>
|
| 335 |
Accept (+) or refuse (-) mails associated to the given keyword(s).
|
| 336 |
Define the list (=) of accepted keywords.
|
| 337 |
|
| 338 |
keyword <srcpackage> [<email>] {+|-|=} <list of keywords>
|
| 339 |
Same as previous item but overrides the keywords list for the indicated
|
| 340 |
source package.
|
| 341 |
|
| 342 |
quit
|
| 343 |
thanks
|
| 344 |
Stops processing commands.
