The Great Unified Tcl/Tk Extension Repository Is an index of Tcl extensions, maintained by Joe English
As of 2012-12, it is being actively updated
LV Too bad there isn't an interface for submitting new entries, or updates to existing entries.
JE Sure there is -- email the administrator :-) Data collection so far has focussed on "pull" mode -- gathering links from existing sources like SF, Freshmeat and Usenet. Once the site goes live, and if it gains traction, and if a solution to the Spam Problem can be devised, then a submission form will probably be added. But that'll happen later, there's a bunch of other stuff to be done first.
LV I don't see anything here or on the web page to indicate who the administrator is, let alone how to email them.
Lars H: A example of what web-based uploads could look like is provided by [%|%CTAN ] (The Comprehensive TeX Archive Network):
Suggestions from SYStems concerning a command-line client moved to Tcl Repository Wish List
RS isn't sure whether the name helps in advertising Tcl: "Oh, you need tdom - just get it from the gutter"
LV Would CANTCL be better advertising?
NEM would like to applaud Joe for spending the effort in getting this set up. Hope it succeeds. It's already looking like a useful resource.
LV Yes, I too want to say thank you for working hard on this.
pmarin What is "tcl repository notes" in the See also section? I only can see a login page.
The author should put the email for adding new packages. I think is a huge effort for only one person.
