[petsc-dev] test harness with alternative output files

[Smith, Barry F.]

   Scott,

    It looks like you started to put in support for the test harness to compare 
output against multiple files.

$ git grep altfile 
config/gmakegentest.py:    if len(altlist)>1: subst['altfiles']=altlist
config/gmakegentest.py:      if 'altfiles' not in subst:
config/gmakegentest.py:        for i in range(len(subst['altfiles'])):
config/gmakegentest.py:          af=subst['altfiles'][i]
config/gmakegentest.py:          if i!=len(subst['altfiles'])-1:

but that there is not yet support for this? 

We have a bunch of tests that require this so we will need it in the test 
harness. How difficult do you think this would be to add?

   Thanks

   Barry
