     This function queries the Curl library to provide information
     about its characteristics when it was compiled. This tells the
     user about its capabilities and can be used to determine
     strategies.

_V_a_l_u_e:

     A list 

     age: integer giving the number of this libcurl, 0 is FIRST, 1 is
          SECOND, 2 is THIRD

 version: the version identifier as a string, e.g. '"7.12.0"'

version_num: the value as an integer

    host: the machine on which the libcurl was configured/built.

features: a named integer vector of bits indicating what features of
          libcurl were configured and built into this version. These
          are features such as ipv6, ssl, libz, largefile, ntlm
          (Microsoft "authorization").

ssl_version: the string identifying the SSL version.

ssl_version_num: the number identifying the SSL version

libz_version: the string identifying the version of libz.

protocols: a character vector of the supported HTTP protocols, e.g.
          http, https, ftp, ldap, gopher, telnet

    ares: name of the asynchronous DNS (domain name service) lookup
          library. This is often simply the empty string indicating it
          is not there. 

ares_num: the number for the ares library

  libidn: the name of the IDN (internationalized domain names) library
          being used. This field only appears in version 3 of libcurl.
          If you are using version 2 (e.g. curl-7.11.2), this will be
          'NA'. An empty string indicates that the field is present,
          but has no value. 


     See the man page for 'curl_version_info' for a description of
     these fields. 'features' in R is a named integer vector detailing
     the different features.
