+ * matrix.tcl: Fixed SF Tcllib #532791 about unsetting of elements
+ in linked arrays as reported by Ken Jones
+ <[email protected]>. Unsetting an element in a linked
+ array now sets the corresponding cell in the matrix to the empty
+ string, and the corresponding elements in other linked arrays
+ are now unset too.
+
* tree.man: New file, doctools manpage.
