+C interface.  Features:
+High-level wrappers for common HTTP and WebDAV operations (GET, MOVE,
+DELETE, etc.);
+low-level interface to the HTTP request/response engine, allowing the use
+of arbitrary HTTP methods, headers, etc.;
+authentication support including Basic and Digest support, along with
+GSSAPI-based Negotiate on Unix, and SSPI-based Negotiate/NTLM on Win32;
+SSL/TLS support using OpenSSL or GnuTLS, exposing an abstraction layer for
+verifying server certificates, handling client certificates, and examining
+certificate properties, smartcard-based client certificates are also
+supported via a PKCS#11 wrapper interface;
+abstract interface to parsing XML using libxml2 or expat, and wrappers for
+simplifying handling XML HTTP response bodies;
+WebDAV metadata support, wrappers for PROPFIND and PROPPATCH to simplify
+property manipulation.")
