Interfacing to an archive web server
A web server providing access to a package archive must support the following queries:
archive-contents
Return a lisp form describing the archive contents. The form is a list of ’package-desc’ structures (see package.el), except the first element of the list is the archive version.
<package name>-readme.txt
Return the long description of the package.
<file name>.sig
Return the signature for the file.
<file name>
Return the file. This will be the tarball for a multi-file package, or the single file for a simple package.
