# class GeneratedPackage

# Enables to deliver whole directories (of generated files) to instdir.

# GeneratedPackage shall be used as a substitution for Package when the
# names of the produced files are not known in advance (in older times,
# we used Zip in these places). It shall only be used to deliver files
# for installation.
#
# If you know the filenames in advance, use Package. Laziness is not an
# excuse.
