|  | # changelog: | 
|  | # 10/13/2005b: replaced the # in tmp(.#*)* with alphanumeric and _, this will then remove | 
|  | # nodes such as %tmp.1.i and %tmp._i.3 | 
|  | # 10/13/2005: exntended to remove variables of the form %tmp(.#)* rather than just | 
|  | #%tmp.#, i.e. it now will remove %tmp.12.3.15 etc, additionally fixed a spelling error in | 
|  | # the comments | 
|  | # 10/12/2005: now it only removes nodes and edges for which the label is %tmp.# rather | 
|  | # than removing all lines for which the lable CONTAINS %tmp.# |
