-== Introduction ==
-
-This SEP proposes a refactoring of !ScrapyManager and !SpiderManager APIs.
-
-== !SpiderManager ==
-
- * get(spider_name) -> Spider instance
- * find_by_request(request) -> list of spider names
- * list() -> list of spider names
-
- * remove: fromdomain(), fromurl()
-
-== !ScrapyManager ==
-
- * crawl_request(request, spider=None)
-   * calls !SpiderManager.find_by_request(request) if spider is None
-     * fails if len(spiders returned) != 1
- * crawl_spider(spider)
-   * calls spider.start_requests()
- * crawl_spider_name(spider_name)
-   * calls !SpiderManager.get(spider_name)
-   * calls spider.start_requests()
- * crawl_url(url)
-   * calls spider.make_requests_from_url()
-
- * remove crawl(), runonce()
-
-Instead of using runonce(), commands (such as crawl/parse) would call crawl_* and then start().
-
-== Changes to Commands ==
-
- * if is_url(arg):
-  * calls !ScrapyManager.crawl_url(arg)
- * else:
-  * calls !ScrapyManager.crawl_spider_name(arg)
-
-== Pending issues ==
-
- * should we rename !ScrapyManager.crawl_* to schedule_* or add_* ?
- * !SpiderManager.find_by_request or !SpiderManager.search(request=request) ?
