One of the many great reasons to attend the Tcl conference is the
tutorials presented by renowned leaders and experts in the Tcl
community. They will be sharing with you their knowledge of Tcl/Tk
and its extensions, and experience in developing large, versatile and
robust applications - information and techniques which will assist you
in your day-to-day Tcl programming needs.
