  Firefox (by running 'make ca-bundle), or by using our online service setup

  for this purpose: http://curl.haxx.se/docs/caextract.html

  There's a bunch of friendly people hanging out in the #curl channel on the

  5.15 How do I get an FTP directory listing? 

  If you end the FTP URL you request with a slash, libcurl will provide you

  with a directory listing of that given directory. You can also set

  CURLOPT_CUSTOMREQUEST to alter what exact listing command libcurl would use

  to list the files.

  The follow-up question that tend to follow the previous one, is how a

  program is supposed to parse the directory listing. How does it know what's

  a file and what's a dir and what's a symlink etc. The harsh reality is that

  FTP provides no such fine and easy-to-parse output. The output format FTP

  servers respond to LIST commands are entirely at the server's own liking and

  the NLST output doesn't reveal any types and in many cases don't even

  include all the directory entries. Also, both LIST and NLST tend to hide

  unix-style hidden files (those that start with a dot) by default so you need

  to do "LIST -a" or similar to see them.

  The application thus needs to parse the LIST output. One such existing

  list parser is available at http://cr.yp.to/ftpparse.html

6. License Issues

  Curl and libcurl are released under a MIT/X derivate license. The license is
