+This directory is for libcurl programming examples. They are meant to show
+some simple steps on how you can build your own application to take full
+advantage of libcurl.
+
+If you end up with other small but still useful example sources, please mail
+them for submission in future packages and on the web site.
+
+BUILDING
+
+The Makefile.example is an example makefile that could be used to build these
+examples. Just edit the file according to your system and requirements first.
+
+Most examples should build fine using a command line like this:
+
+  $ `curl-config --cc --cflags --libs` -o example example.c
+
+Some compilers don't like having the arguments in this order but instead
+want you do reorganize them like:
+
+  $ `curl-config --cc` -o example example.c `curl-config --cflags --libs`
+
+*PLEASE* do not use the curl.haxx.se site as a test target for your libcurl
+applications/experiments. Even if some of the examples use that site as a URL
+at some places, it doesn't mean that the URLs work or that we expect you to
+actually torture our web site with your tests!  Thanks.
+
+EXAMPLES
+
+Each example source code file is designed to be and work stand-alone and
+rather self-explanatory. The examples may at times lack the level of error
+checks you need in a real world, but that is then only for the sake of
+readability: to make the code smaller and easier to follow.

+
+Requires libev and a (POSIX?) system that has mkfifo().
+
+This is an adaptation of libcurl's "hipev.c" and libevent's "event-test.c"
+sample programs.
+
+When running, the program creates the named pipe "hiper.fifo"
+
+Whenever there is input into the fifo, the program reads the input as a list
+of URL's and creates some new easy handles to fetch each URL via the
+curl_multi "hiper" API.
+
+
+Thus, you can try a single URL:
+  % echo http://www.yahoo.com > hiper.fifo
+
+Or a whole bunch of them:
+  % cat my-url-list > hiper.fifo
+
+The fifo buffer is handled almost instantly, so you can even add more URL's
+while the previous requests are still being downloaded.
+
+Note:
+  For the sake of simplicity, URL length is limited to 1023 char's !
+
+This is purely a demo app, all retrieved data is simply discarded by the write
+callback.

+/*****************************************************************************
+ *
+ * This example source code introduces a c library buffered I/O interface to
+ * URL reads it supports fopen(), fread(), fgets(), feof(), fclose(),
+ * rewind(). Supported functions have identical prototypes to their normal c
+ * lib namesakes and are preceaded by url_ .
+ *
+ * Using this code you can replace your program's fopen() with url_fopen()
+ * and fread() with url_fread() and it become possible to read remote streams
+ * instead of (only) local files. Local files (ie those that can be directly
+ * fopened) will drop back to using the underlying clib implementations
+ *
+ * See the main() function at the bottom that shows an app that retrieves from
+ * a specified url using fgets() and fread() and saves as two output files.

+ Requires glib-2.x and a (POSIX?) system that has mkfifo().

+ This is an adaptation of libcurl's "hipev.c" and libevent's "event-test.c"
+ sample programs, adapted to use glib's g_io_channel in place of libevent.
+
+ When running, the program creates the named pipe "hiper.fifo"
+
+ Whenever there is input into the fifo, the program reads the input as a list
+ of URL's and creates some new easy handles to fetch each URL via the
+ curl_multi "hiper" API.
+
+
+ Thus, you can try a single URL:
+ % echo http://www.yahoo.com > hiper.fifo
+
+ Or a whole bunch of them:
+ % cat my-url-list > hiper.fifo
+
+ The fifo buffer is handled almost instantly, so you can even add more URL's
+ while the previous requests are still being downloaded.
+
+ This is purely a demo app, all retrieved data is simply discarded by the write

+/* This example code only builds as-is on Windows.
+ *
+ * While Unix/Linux user, you do not need this software.
+ * You can achieve the same result as synctime using curl, awk and date.
+ * Set proxy as according to your network, but beware of proxy Cache-Control.
+ *
+ * To set your system clock, root access is required.
+ * # date -s "`curl -sI http://nist.time.gov/timezone.cgi?UTC/s/0 \
+ *        | awk -F': ' '/Date: / {print $2}'`"
+ *
+ * To view remote webserver date and time.
+ * $ curl -sI http://nist.time.gov/timezone.cgi?UTC/s/0 \
+ *        | awk -F': ' '/Date: / {print $2}'
+ *
+ * Synchronising your computer clock via Internet time server usually relies
+ * on DAYTIME, TIME, or NTP protocols. These protocols provide good accurate
+ * time synchronisation but it does not work very well through a
+ * firewall/proxy. Some adjustment has to be made to the firewall/proxy for
+ * these protocols to work properly.
+ *
+ * There is an indirect method. Since most webserver provide server time in
+ * their HTTP header, therefore you could synchronise your computer clock
+ * using HTTP protocol which has no problem with firewall/proxy.
+ *
+ * For this software to work, you should take note of these items.
+ * 1. Your firewall/proxy must allow your computer to surf internet.
+ * 2. Webserver system time must in sync with the NTP time server,
+ *    or at least provide an accurate time keeping.
+ * 3. Webserver HTTP header does not provide the milliseconds units,
+ *    so there is no way to get very accurate time.
+ * 4. This software could only provide an accuracy of +- a few seconds,
+ *    as Round-Trip delay time is not taken into consideration.
+ *    Compensation of network, firewall/proxy delay cannot be simply divide
+ *    the Round-Trip delay time by half.
+ * 5. Win32 SetSystemTime() API will set your computer clock according to
+ *    GMT/UTC time. Therefore your computer timezone must be properly set.
+ * 6. Webserver data should not be cached by the proxy server. Some
+ *    webserver provide Cache-Control to prevent caching.
+ *
+ * References:
+ * http://tf.nist.gov/timefreq/service/its.htm
+ * http://tf.nist.gov/timefreq/service/firewall.htm
+ *
+ * Usage:
+ * This software will synchronise your computer clock only when you issue
+ * it with --synctime. By default, it only display the webserver's clock.
