+** curl 7.7 DOES NOT currently WORK. **
+
+Daniel (4 March 2001)
+- Now, there's even a basic check that a re-used connection is still alive
+  before it is assumed so. A few first tests have proven that libcurl will
+  then re-connect instead of re-use the dead connection!
+
+Daniel (2 March 2001)
+- Now they work intermixed as well. Major coolness!
+
+- More fiddling around, my 'tiny' client I have for testing purposes now has
+  proved to download both FTP and HTTP with persistant connections. They do
+  not work intermixed yet though.
+
+Daniel (1 March 2001)
+- Wilfredo Sanchez pointed out a minor spelling mistake in a man page and that
+  curl_slist_append() should take a const char * as second argument. It does
+  now.
+
+Daniel (22 February 2001)
+- The persistant connections start to look good for HTTP. On a subsequent
+  request, it seems that libcurl now can pick an already existing connection
+  if a suitable one exists, or it opens a new one.
+
+- Douglas R. Horner mailed me corrections to the curl_formparse() man page
+  that I applied.
+
+Daniel (20 February 2001)
+- Added the docs/examples/win32sockets.c file for our windows friends.
+
+- Linus Nielsen Feltzing provided brand new TELNET functionality and
+  improvements:
+
+  * Negotiation is now passive. Curl does not negotiate until the peer does.
+  * Possibility to set negotiation options on the command line, currently only
+    XDISPLOC, TTYPE and NEW_ENVIRON (called NEW_ENV).
+  * Now sends the USER environment variable if the -u switch is used.
+  * Use -t to set telnet options (Linus even updated the man page, awesome!)
+
+- Haven't done this big changes to curl for a while. Moved around a lot of
+  struct fields and stuff to make multiple connections get connection specific
+  data in separate structs so that they can co-exist in a nice way. See the
+  mailing lists for discussions around how this is gonna be implemented. Docs
+  and more will follow.
+
+  Studied the HTTP RFC to find out better how persistant connections should
+  work. Seems cool enough.
+
+Daniel (19 February 2001)
+- Bob Schader brought me two files that help set up a MS VC++ libcurl project
+  easier. He also provided me with an up-to-date libcurl.def file.
+
+- I moved a bunch of prototypes from the public <curl/curl.h> file to the
+  library private urldata.h. This is because of the upcoming changes. The
+  low level interface is no longer being planned to become reality.
+
+Daniel (15 February 2001)
+- CURLOPT_POST is not required anymore. Just setting the POST string with
+  CURLOPT_POSTFIELDS will switch on the HTTP POST. Most other things in
+  libcurl already works this way, i.e they require only the parameter to
+  switch on a feature so I think this works well with the rest. Setting a NULL
+  string switches off the POST again.
+
+- Excellent suggestions from Rich Gray, Rick Jones, Johan Nilsson and Bjorn
+  Reese helped me define a way how to incorporate persistant connections into
+  libcurl in a very smooth way. If done right, no change may have to be made
+  to older programs and they will just start using persistant connections when
+  applicable!
+
+Daniel (13 February 2001)
+- Changed the word 'timeouted' to 'timed out' in two different error messages.
+  Suggested by Larry Fahnoe.
+

- *
- * This function asks for the particular document, file or resource that

- * just an absolute path or even a relative path. That means, if you're just
- * getting one file from the remote site, you can use the same URL as input

- *
- * In the even there is a host name, port number, user name or password parts
- * in the URL, you can use the 'flags' argument to ignore them completely, or
- * at your choice, make the function fail if you're trying to get a URL from
- * different host than you connected to with curl_connect().
- *
- * You can only get one document at a time using the same connection. When one
- * document has been received you can although request again.
- *
- * When the transfer is done, curl_done() MUST be called.

+ * NAME curl_do()
+ *
+ * DESCRIPTION
+ *
+ * (Note: May 3rd 2000: this function does not currently allow you to
+ * specify a document, it will use the one set previously)
+ *
+ * This function asks for the particular document, file or resource that
+ * resides on the server we have connected to. You may specify a full URL,
+ * just an absolute path or even a relative path. That means, if you're just
+ * getting one file from the remote site, you can use the same URL as input
+ * for both curl_open() as well as for this function.
+ *
+ * In the even there is a host name, port number, user name or password parts
+ * in the URL, you can use the 'flags' argument to ignore them completely, or
+ * at your choice, make the function fail if you're trying to get a URL from
+ * different host than you connected to with curl_connect().
+ *
+ * You can only get one document at a time using the same connection. When one
+ * document has been received you can although request again.
+ *
+ * When the transfer is done, curl_done() MUST be called.
+ *
+ * EXAMPLE
+ *
+ * CURLCode result;
+ * char *url;
+ * CURLconnect *connect;
+ * result = curl_do(connect, url, CURL_DO_NONE); */

+ * get called.
+ *

+ *
+ * CURLCode result;
+ * char *url;
+ * CURLconnect *connect;
