The $summary section of the input file will cause a SUMMARY.txt file to be printed into the recipe directory, once the recipe is complete.
Each line in the summary section follows the format:
<ingredient name search string> <summary information>
<search string> is a search string for matching ingredient names.
<summary information> refers to a python file in <MAST installation directory>/summary which is supposed to extract information from a given ingredient directory.
For example, the following section would extract energies from each ingredient matching vac in its name.
$summary vac energy $end
