Ivy housekeeping, repository cleaning

[Gerke Ephorus]

 Hi list readers,

I have an Ivy repository and according to this: 
http://ant.apache.org/ivy/history/latest-milestone/bestpractices.html 
section "Dealing with integration versions", I'm using a timestamp link 
name in the artifact name to store the latest.integration. Now the 
repository is very big (almost 50G) and I probably need a "cleaning 
script" as also suggested in the above mentioned section.

My question is: does any one use this strategy and if so: does (that ;-) 
)anyone know of a script that will clean-up my repository? (leaving in 
it: only the newest artifacts and the release-builds that have a 
different file name pattern)

with kind regards,
Gerke
