/* Done:
- * - works with http only
+ * - works with http (only!)
* - always picks the first mirror from the list
* - call out to problem reporting script
* - supports "deb mirror://host/path/to/mirror-list/// dist component"
+ * - uses pkgAcqMethod::FailReason() to have a string representation
+ * of the failure that is also send to LP
*
* TODO:
- * what about gpgv failures? this should call-out to the problem reporting
- script, but we need to know what mirror was used
- * better standard format for errors to send back
- * - implement failure reporting at the pkgAcquire::Item::Failed() level
- but then we need to send back what uri exactly was failing
- [mvo: the problem with this approach is ::Failed() is not really
- called for all failures :/ e.g. md5sum mismatch in a archive
- is not]
* - deal with runing as non-root because we can't write to the lists
dir then -> use the cached mirror file
* - better method to download than having a pkgAcquire interface here
- * - magicmarker is (a bit) evil, maybe just use a similar approach as in
- clean and read the sources.list and use the GetURI() method to find
- the prefix?
- * support more than http
+ * and better error handling there!
+ * - support more than http
* - testing :)
