-.SH NAME
-unset \- Delete variables
-.SH SYNOPSIS
-\fBunset \fR?\fI\-nocomplain\fR? ?\fI\-\-\fR? ?\fIname name name ...\fR?
-.BE
-.SH DESCRIPTION
-.PP
-This command removes one or more variables.
-Each \fIname\fR is a variable name, specified in any of the
-ways acceptable to the \fBset\fR command.
-If a \fIname\fR refers to an element of an array then that
-element is removed without affecting the rest of the array.
-If a \fIname\fR consists of an array name with no parenthesized
-index, then the entire array is deleted.
-The \fBunset\fR command returns an empty string as result.
-If \fI\-nocomplain\fR is specified as the first argument, any possible
-errors are suppressed.  The option may not be abbreviated, in order to
-disambiguate it from possible variable names.  The option \fI\-\-\fR
-indicates the end of the options, and should be used if you wish to
-remove a variable with the same name as any of the options.
-If an error occurs, any variables after the named one causing the error not
-deleted.  An error can occur when the named variable does not exist, or the
-name refers to an array element but the variable is a scalar, or the name
-refers to a variable in a non-existent namespace.
-.SH EXAMPLE
-Create an array containing a mapping from some numbers to their
-squares and remove the array elements for non-prime numbers:
-.CS
-array set squares {
-    1 1    6 36
-    2 4    7 49
-    3 9    8 64
