Overview;T@o;	;[I"OXMLRPC is a lightweight protocol that enables remote procedure calls over ;TI"3HTTP.  It is defined at http://www.xmlrpc.com.;T@o;	;[I"RXMLRPC allows you to create simple distributed computing solutions that span ;TI"Pcomputer languages.  Its distinctive feature is its simplicity compared to ;TI"*other approaches like SOAP and CORBA.;T@o;	;[I"TThe Ruby standard library package 'xmlrpc' enables you to create a server that ;TI"Rimplements remote procedures and a client that calls them.  Very little code ;TI",is required to achieve either of these.;T@S;
