+.SH NAME
+global \- Access global variables
+.SH SYNOPSIS
+\fBglobal \fIvarname \fR?\fIvarname ...\fR?
+.BE
+
+.SH DESCRIPTION
+.PP
+This command is ignored unless a Tcl procedure is being interpreted.
+If so then it declares the given \fIvarname\fR's to be global variables
+rather than local ones.
+Global variables are variables in the global namespace.
+For the duration of the current procedure
+(and only while executing in the current procedure),
+any reference to any of the \fIvarname\fRs
+will refer to the global variable by the same name.
+
