From Rosetta Code
Library: Tcllib (Package: {{{1}}})

This template is for tagging Tcl solutions by the packages within the Tcllib library they use. It adds both a link to the page for the Tcllib library and a category of the same name.

If the package isn't part of tcllib, please use the {{libheader}} template instead.

This is a template. There are many others. See Category:RCTemplates for a complete list of templates.
