added some more text about libcurl using

 When using the easy interface, you init your easy-session and get a handle,

 which you use as input to the following interface functions you use.

 You continue be setting all the options you want in the upcoming transfer,

 You continue by setting all the options you want in the upcoming transfer,

 most important among them is the URL itself. You might want to set some

 callbacks as well that will be called from the library when data is available

 etc.

 When all is setup, you tell libcurl to perform the transfer. It will then do

 the entire operation and won't return until it is done or failed.

 After the performance is made, you cleanup the easy-session's handle and

 libcurl is entire off the hook!

 See the separate man pages for the libcurl functions for details:

        curl_easy_init() 

        curl_easy_setopt() 

        curl_easy_perform() 

        curl_easy_cleanup() 

 While the above four functions are the main functions to use in the easy

 interface, there is a series of helpful functions to use. They are:

        curl_version()        - displays the libcurl version

        curl_getdate()        - converts a date string to time_t

        curl_getenv()         - portable environment variable reader

        curl_formparse()      - helps building a HTTP form POST

        curl_slist_append()   - builds a linked list

        curl_slist_free_all() - frees a whole curl_slist
