# * package
# objects in this package (and possibly sub-packages,

# from source into a single object, using the C++ ABI.
# * ordinary

# if they do not appear in the map) will be compiled one at
# a time into separate .o files.
# * ignore
# objects in this package are not used. Note however that
# most ignored files are actually handled by listing them in
# 'standard.omit'

# If a package does not appear in the map, the default is 'package'.
