Hi, are you ready for a ****?
If you know that there will only be small changes, you could do the following:
copy yourReal.lib into libHeader.lib
open libHeader.lib and locate the first cell description
delete everything from the first cell to the last line and save the file
change the library name (near the top) to myNewCell
copy yourReal.lib into myCell.lib
open myCell.lib and locate the cell that is similar to your new cell
delete everything above this cell
goto the end of the cell and delete everything below this cell
modify myCell.lib to reflect your changes
copy libHeader.lib into myNewLib.lib
open myNewLib.lib and include the updated myCell.lib
be sure you "end" the file properly
now test to be sure you have the correct syntax in your file
