The latest version of cURL, 7.18.0, has been released for OpenVMS
and is available for download.

The location is http://curl.haxx.se/download.html#VMS

This is the binary and object library distribution of the cURL
7.18.0 release. See the readme.vms file in the zip for usage
information. The zip files contain executables and objects built
with OpenSSL, hpSSL and without SSL support. The files are in
architecture specific zips.

The OpenSSL and noSSL versions are self-contained in that you can
run these programs without any other software on the system. For
the hp SSL version, you will need to have hp's matching SSL product
installed.

For those who don't know what cURL is, here is the blurb from their main
page...

Curl is a command line tool for transferring files with
URL syntax, supporting FTP, FTPS, HTTP, HTTPS, GOPHER,
TELNET, DICT, FILE and LDAP. Curl supports HTTPS
certificates, HTTP POST, HTTP PUT, FTP uploading,
kerberos, HTTP form based upload, proxies, cookies,
user+password authentication, file transfer resume, http
proxy tunneling and a busload of other useful tricks.

I haven't tested all the features, since I only use the library for
HTTP(S) stuff via C programs. It does compile and link cleanly on all
the platforms outlined above.
