If the target platform is win32, create .bat files...
...instead of *nix shell scripts.
Target platform is set to "win32" if main command is 'bdist_wininst'
or if the command is 'bdist' and it has the list of formats (from
command line or config file) and the first item on that list is wininst.
Otherwise target platform is set to current (build) platform.

| 372 What you can't do to the schema | |
| 373 ------------------------------- | |
| 374 | |
| 375 You must never: | |
| 376 | |
| 377 **Remove the users class** | |
| 378 This class is the only *required* class in Roundup. Similarly, its | |
| 379 username, password and address properties must never be removed. | |
| 380 | |
| 381 **Change the type of a property** | |
| 382 Property types must *never* be changed - the database simply doesn't take | |
| 383 this kind of action into account. Note that you can't just remove a | |
| 384 property and re-add it as a new type either. If you wanted to make the | |
| 385 assignedto property a Multilink, you'd need to create a new property | |
| 386 assignedto_list and remove the old assignedto property. | |
| 387 | |
| 388 | |
| 389 What you can do to the schema | |
| 390 ----------------------------- | |
| 391 | |
| 392 Your schema may be changed at any time before or after the tracker has been | |
| 393 initialised (or used). You may: | |
| 394 | |
| 395 **Add new properties to classes, or add whole new classes** | |
| 396 This is painless and easy to do - there are generally no repurcussions | |
| 397 from adding new information to a tracker's schema. | |
| 398 | |
| 399 **Remove properties** | |
| 400 Removing properties is a little more tricky - you need to make sure that | |
| 401 the property is no longer used in the `web interface`_ *or* by the | |
| 402 detectors_. | |

| 589 Detector API | |
| 590 ------------ | |
| 591 | |
| 592 Auditors are called with the arguments:: | |
| 593 | |
| 594 audit(db, cl, itemid, newdata) | |
| 595 | |
| 596 where ``db`` is the database, ``cl`` is an instance of Class or | |
| 597 IssueClass within the database, and ``newdata`` is a dictionary mapping | |
| 598 property names to values. | |
| 599 | |
| 600 For a ``create()`` operation, the ``itemid`` argument is None and | |
| 601 newdata contains all of the initial property values with which the item | |
| 602 is about to be created. | |
| 603 | |
| 604 For a ``set()`` operation, newdata contains only the names and values of | |
| 605 properties that are about to be changed. | |
| 606 | |
| 607 For a ``retire()`` or ``restore()`` operation, newdata is None. | |
| 608 | |
| 609 Reactors are called with the arguments:: | |
| 610 | |
| 611 react(db, cl, itemid, olddata) | |
| 612 | |
| 613 where ``db`` is the database, ``cl`` is an instance of Class or | |
| 614 IssueClass within the database, and ``olddata`` is a dictionary mapping | |
| 615 property names to values. | |
| 616 | |
| 617 For a ``create()`` operation, the ``itemid`` argument is the id of the | |
| 618 newly-created item and ``olddata`` is None. | |
| 619 | |
| 620 For a ``set()`` operation, ``olddata`` contains the names and previous | |
| 621 values of properties that were changed. | |
| 622 | |
| 623 For a ``retire()`` or ``restore()`` operation, ``itemid`` is the id of | |
| 624 the retired or restored item and ``olddata`` is None. | |

1853 The form variable is a bit special because it's actually a python |
| 1142 | 1854 FieldStorage object. That means that you have two ways to access its |
| 1855 contents. For example, to look up the CGI form value for the variable | |
| 1856 "name", use the path expression:: | |
| 1857 | |
| 1858 request/form/name/value | |
| 1859 | |
| 1860 or the python expression:: | |
| 1861 | |
| 1862 python:request.form['name'].value | |
