different versions of getopt on various OSes make writing portable shell
scripts difficult.  shFlags instead provides an API that doesn't change across
shell and OS versions so the script writer can be confident that the script
will work.")

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.")
