套件： libdata-flow-perl (1.02-2)

Perl extension for simple-minded recipe-controlled build of data

Data::Flow allows you to define recipes for building data. A recipe contains all of the rules for determining the value of the data involved based on a set of defaults and/or interreactions with other pieces of data in an automated fashion. You can define any or all of:

 - default values
 - prerequisites (other fields that must have values before the field
   in question can be determined)
 - subroutines to build the field data given all requirements
