-.SH NAME
-case \- Evaluate one of several scripts, depending on a given value
-.SH SYNOPSIS
-\fBcase\fI string \fR?\fBin\fR? \fIpatList body \fR?\fIpatList body \fR...?
-.sp
-\fBcase\fI string \fR?\fBin\fR? {\fIpatList body \fR?\fIpatList body \fR...?}
-.BE
-
-.SH DESCRIPTION
-.PP
-\fINote: the \fBcase\fI command is obsolete and is supported only
-for backward compatibility.  At some point in the future it may be
-removed entirely.  You should use the \fBswitch\fI command instead.\fR
-.PP
-The \fBcase\fR command matches \fIstring\fR against each of
-the \fIpatList\fR arguments in order.
-Each \fIpatList\fR argument is a list of one or
-more patterns.  If any of these patterns matches \fIstring\fR then
-\fBcase\fR evaluates the following \fIbody\fR argument
-by passing it recursively to the Tcl interpreter and returns the result
-of that evaluation.
-Each \fIpatList\fR argument consists of a single
-pattern or list of patterns.  Each pattern may contain any of the wild-cards
-described under \fBstring match\fR.  If a \fIpatList\fR
-argument is \fBdefault\fR, the corresponding body will be evaluated
-if no \fIpatList\fR matches \fIstring\fR.  If no \fIpatList\fR argument
-matches \fIstring\fR and no default is given, then the \fBcase\fR
-command returns an empty string.
-.PP
-Two syntaxes are provided for the \fIpatList\fR and \fIbody\fR arguments.
-The first uses a separate argument for each of the patterns and commands;
-this form is convenient if substitutions are desired on some of the
-patterns or commands.
-The second form places all of the patterns and commands together into
-a single argument; the argument must have proper list structure, with
-the elements of the list being the patterns and commands.
-The second form makes it easy to construct multi-line case commands,
-since the braces around the whole list make it unnecessary to include a
-backslash at the end of each line.
-Since the \fIpatList\fR arguments are in braces in the second form,
-no command or variable substitutions are performed on them;  this makes
-the behavior of the second form different than the first form in some
-cases.
