Utility: rpdiff

The rpdiff command compares two run.xml files and reports differences in their output sections:

rpdiff run1.xml run2.xml

Returns 0 exit status if the two files have the same output. Returns non-zero exit status if the outputs differ, along with a list of differences on stdout.

Useful for checking the results of multiple runs of the same simulation, to ensure that they are consistent. Under BOINC, for example, the same job may be sent off to multiple volunteers, and the results are compared to ensure that all volunteers are reporting consistent (trustworthy) results.
