| #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.# |
