# A script to compare the provenance of two input root files.
|
| 4 |
# It prints out informations about those modules which are common to the input files,
|
| 5 |
# but whose parameters are set to different values, and about those modules
|
| 6 |
# present only in one of the two files.
|
| 7 |
# According to the level of verbosity, it will be report the name of these modules
|
| 8 |
# and details about the parameters and their values.
