Information about extensions for Tcl
. This should be thought of as a counterpart to Applications in Tcl and Tcl/Tk
. Add URLs, descriptions, and warnings about various useful extensions.
There is such strong growth of wonderful extensions to Tcl that an interactive facility such as that provided here on The Tcler's Wiki is needed for authors to add their own categories and links to the home pages for their applications. Feel free to add categories to those already on the page. Please keep descriptions brief, and always
link to a download site at a minimum, but preferably to the homepage for your application.

The idea of one page like this, pointing to a variety of other pages here on the wiki as well as other web sites, has been advocated over the years as being a preferred method of interacting with the wiki's data. For those who find this the case, I encourage you to continue adding to the above catalog of extensions.
To those of you who prefer working with the wiki's categories, it might be useful to consider whether the pages describing the various extensions have sufficiently been categorized, or if additional categories are needed.
