|
#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.#
