Purpose: provide a launching point for explanations and suggestions for resolving warnings and errors generated by the base Tcl interpreter.
Similar pages for extensions can be started if this appears useful.
The following is an attempt to catalog the various warning messages that a user might find appearing when running Tcl applications. The purpose of this list is not to simply have a list. It is to provide a point where people can add more explanation as to what a particular warning or error means, along with suggestions for solving the situation. In some cases, the solution may be a change in the user's environment. In other cases, the message may indicate an error in the Tcl application. In a few cases, the messag may indicate a problem in Tcl itself.
