+   HTTP Aquire Method - This is the HTTP aquire method for APT.
+   
+   It uses HTTP/1.1 and many of the fancy options there-in, such as
+   pipelining, range, if-range and so on. It accepts on the command line
+   a list of url destination pairs and writes to stdout the status of the
+   operation as defined in the APT method spec.
+   
+   It is based on a doubly buffered select loop. All the requests are 
+   fed into a single output buffer that is constantly fed out the 
+   socket. This provides ideal pipelining as in many cases all of the
+   requests will fit into a single packet. The input socket is buffered 
+   the same way and fed into the fd for the file.
+   
+   This double buffering provides fairly substantial transfer rates,
+   compared to wget the http method is about 4% faster. Most importantly,
+   when HTTP is compared with FTP as a protocol the speed difference is
+   huge. In tests over the internet from two sites to llug (via ATM) this
+   program got 230k/s sustained http transfer rates. FTP on the other 
+   hand topped out at 170k/s. That combined with the time to setup the
+   FTP connection makes HTTP a vastly superior protocol.
