+The methods supplied by the stock apt are:
+<enumlist>
+<item>cdrom - For Multi-Disc CDROMs
+<item>copy - (internal) For copying files around the filesystem
+<item>file - For local files
+<item>gzip - (internal) For decompression
+<item>http - For HTTP servers
+</enumlist>
+
+<p>
+The two internal methods, copy and gzip, are used by the acquire code to
+parallize and simplify the automatic decompression of package files as well 
+as copying package files around the file system. Both methods can be seen to 
+act the same except that one decompresses on the fly. APT uses them by
+generating a copy URI that is formed identically to a file URI. The destination
+file is send as normal. The method then takes the file specified by the 
+URI and writes it to the destination file. A typical set of operations may
+be:
+<example>
+http://foo.com/Packages.gz -> /bar/Packages.gz
+gzip:/bar/Packages.gz -> /bar/Packages.decomp
+rename Packages.decomp to /final/Packages
+</example>
+
+<p>
+The http method implements a fully featured HTTP/1.1 client that supports
+deep pipelining and reget. It works best when coupled with an apache 1.3
+server. The file method simply generates failures or success responses with
+the filename field set to the proper location. The cdrom method acts the same
+except that it checks that the mount point has a valid cdrom in it. It does 
+this by (effectively) computing a md5 hash of 'ls -l' on the mountpoint.
