-Pingpong
-========
-
- Pingpong is just my (Daniel's) jestful collective name on the protocols that
- share a very similar kind of back-and-forth procedure with command and
- responses to and from the server. FTP was previously the only protocol in
- that family that libcurl supported, but when POP3, IMAP and SMTP joined the
- team I moved some of the internals into a separate pingpong module to be
- easier to get used by all these protocols to reduce code duplication and ease
- code re-use between these protocols.
-
-FTP
-
- In 7.20.0 we converted code to use the new pingpong code from previously
- having been all "native" FTP code.
-
-POP3
-
- There's no support in the documented URL format to specify the exact mail to
- get, but we support that as the path specified in the URL.
-
-IMAP
-
-SMTP
-
- There's no official URL syntax defined for SMTP, but we use only the generic
- one and we provide two additional libcurl options to specify receivers and
- sender of the actual mail.
