Amongst standard functions it supports there are SSL certificates, HTTP POST, HTTP PUT, FTP uploading, HTTP form based upload, proxies, cookies, user+password authentication (Basic, Digest, NTLM, Negotiate, Kerberos), file transfer resume, http proxy tunneling and so on.
Unusually enough the project provides bindings for a number of other languages and toolkits including Ada95, Basic, C, C++, Ch, Cocoa, D, Dylan, Eiffel, Euphoria, Falcon, Ferite, Gambas, glib/GTK+, Guile, Haskell, ILE/RPG, Java, Lisp, Lua, Mono, .NET, node.js, Object-Pascal (Delphi), OCaml, Pascal, Perl, PHP, PostgreSQL, Python, R, Rexx (As REXX/CURL), Ruby, Scheme, S-Lang, Smalltalk, SP-Forth, SPL, Tcl, Visual Basic, Visual FoxPro, Q, wxWidgets and XBLite.
It should be noted though that the existence of a binding for a language or tool does not automatically mean that you can use it as is, you preferred version of the tool may need some massaging before working as expected.
