This is a really hacky plugin for spiffy that allows you to serve
automatically-generated release-info files and files-list files
(the latter of which serves as the files section of a meta-file)
for an SVN repository.

It assumes the svn repository location contains a toplevel directory
named after the major CHICKEN release, with subdirectories matching
the names of eggs.  Those egg directories contain a "tags" directory
for each revision, with the revision number as its name:

 /4
   /MY-EGG
     /tags
       /1.0
       /1.1
   /ANOTHER-EGG
     /tags
       /0.1
       /0.2
       /1.0
 /5
   /MY-EGG
     /tags
       /2.0
       /2.1
   /SOME-NEWER-EGG
     /tags
       /0.1


You can use it like this:

(use spiffy spiffy-uri-match pseudo-meta-egg-info)

;; Trailing slash is mandatory here!
;; The {chicken-release} placeholder gets replaced by the major CHICKEN version.
;; By default this uses the Chicken repo.
(egg-repo "http://example.com/your-egg-repo/eggs/release/{chicken-release}/")

(vhost-map `((".*" 
              . ,(uri-match/spiffy
                  `(((/ "release-info") (GET ,release-info))
                    ((/ "files-list")   (GET ,files-list)))))))
(start-server)


This makes the release-info for the CHICKEN 4 version of egg MY-EGG, available under
http://localhost:8080/release-info?egg=MY-EGG;release=4

and the files-list for release 1.0 for the CHICKEN 5 version of MY-EGG under
http://localhost:8080/files-list?egg=MY-EGG;release=1.0;release=5
