Hey Emacs, this is -*- outline -*- modeThis is the to-do list for GNU Wget.  There is no timetable of when weplan to implement these features -- this is just a list of featureswe'd like to see in Wget, as well as a list of problems that needfixing.  Patches to implement these items are likely to be accepted,especially if they follow the coding convention outlined in PATCHESand if they patch the documentation as well.The items are not listed in any particular order (except thatrecently-added items may tend towards the top).  Not all of theserepresent user-visible changes.* Honor `Content-Disposition: XXX; filename="FILE"' when creating the  file name.  If possible, try not to break `-nc' and friends when  doing that.* Wget shouldn't delete rejected files that were not downloaded, but  just found on disk because of `-nc'.  For example, `wget -r -nc  -A.gif URL' should allow the user to get all the GIFs without  removing any of the existing HTML files.* Be careful not to lose username/password information given for the  URL on the command line.* Add a --range parameter allowing you to explicitly specify a range  of bytes to get from a file over HTTP (FTP only supports ranges  ending at the end of the file, though forcibly disconnecting from  the server at the desired endpoint might be workable).* If multiple FTP URLs are specified that are on the same host, Wget should  re-use the connection rather than opening a new one for each file.* Try to devise a scheme so that, when password is unknown, Wget asks  the user for one.* If -c used with -N, check to make sure a file hasn't changed on the server  before "continuing" to download it (preventing a bogus hybrid file).* Generalize --html-extension to something like --mime-extensions and  have it look at mime.types/mimecap file for preferred extension.  Non-HTML files with filenames changed this way would be  re-downloaded each time despite -N unless .orig files were saved for  them.  Since .orig would contain the same data as non-.orig, the  latter could be just a link to the former.  Another possibility  would be to implement a per-directory database called something like  .wget_url_mapping containing URLs and their corresponding filenames.* When spanning hosts, there's no way to say that you are only interested in  files in a certain directory on _one_ of the hosts (-I and -X apply to all).  Perhaps -I and -X should take an optional hostname before the directory?* --retr-symlinks should cause wget to traverse links to directories too.* Make wget return non-zero status in more situations, like incorrect HTTP auth.* Make -K compare X.orig to X and move the former on top of the latter if   they're the same, rather than leaving identical .orig files laying around.* Make `-k' check for files that were downloaded in the past and convert links   to them in newly-downloaded documents.* Add option to clobber existing file names (no `.N' suffixes).* Add option to only list wildcard matches without doing the download.* Handle MIME types correctly.  There should be an option to (not)  retrieve files based on MIME types, e.g. `--accept-types=image/*'.* Allow time-stamping by arbitrary date.* Allow size limit to files (perhaps with an option to download oversize files   up through the limit or not at all, to get more functionality than [u]limit.* Download to .in* when mirroring.* Add an option to delete or move no-longer-existent files when mirroring.* Implement uploading (--upload URL?) in FTP and HTTP.* Rewrite FTP code to allow for easy addition of new commands.  It  should probably be coded as a simple DFA engine.* Make HTTP timestamping use If-Modified-Since facility.* Add more protocols (e.g. gopher and news), implementing them in a  modular fashion.* Add a "rollback" option to have continued retrieval throw away a  configurable number of bytes at the end of a file before resuming  download.  Apparently, some stupid proxies insert a "transfer  interrupted" string we need to get rid of.
