| # 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 label CONTAINS %tmp.# | |
