[PD] web update of pd-extended

[patrick]

hi hans & all,

i am working on a small software with wxwidgets and came across a 
solution for updating the package, the software or the updater via http. 
it's cross platform and very flexible to my eyes. i am just proposing 
this solution for pd-extended, that way people who wants to upgrade, 
just need to launch the "web update" (listing the externals that are 
new, updated, documentation etc...).

http://wxcode.sourceforge.net/docs/webupdate/

i am sure there's other open source solution out there.
