+README
+
+  Curl is a command line tool for transferring data specified with URL
+  syntax. Find out how to use curl by reading the curl.1 man page or the
+  MANUAL document. Find out how to install Curl by reading the INSTALL
+  document.
+
+  libcurl is the library curl is using to do its job. It is readily
+  available to be used by your software. Read the libcurl.3 man page to
+  learn how!
+
+  You find answers to the most frequent questions we get in the FAQ document.
+
+  Study the COPYING file for distribution terms and similar. If you distribute
+  curl binaries or other binaries that involve libcurl, you might enjoy the
+  LICENSE-MIXING document.
+
+CONTACT
+
+  If you have problems, questions, ideas or suggestions, please contact us
+  by posting to a suitable mailing list. See http://curl.haxx.se/mail/
+
+  All contributors to the project are listed in the THANKS document.
+
+WEB SITE
+
+  Visit the curl web site for the latest news and downloads:
+
+        http://curl.haxx.se/
+
+GIT
+
+  To download the very latest source off the GIT server do this:
+
+    git clone git://github.com/bagder/curl.git
+
+  (you'll get a directory named curl created, filled with the source code)
