+  To specify a command line option that includes spaces, you might need to
+  put the entire option within quotes. Like in:
+
+   curl -d " with spaces " url.com
+  
+  or perhaps
+
+   curl -d ' with spaces ' url.com
+
+  Exactly what kind of quotes and how to do this is entirely up to the shell
+  or command line interepreter that you are using. For most unix shells, you
+  can more or less pick either single (') or double (") quotes. For
+  Windows/DOS prompts I believe you're forced to use double (") quotes.

+  adjust them to work in your environment.
+
+  Remember that curl works and runs on more operating systems than most
+  individuals have ever tried.
