# \brief Utilities for generating and checking port hashes

|
# The hash depends on the content of the port description file and the
|
|
# patches originating from REP_DIR. Patches that are downloaded are already
|
|
# captured by the hash sums of the downloaded files, which are declared in the
|
|
# port description file.
|
|
#
|
|
# During development when the files of MAKEFILE_LIST often change, the
|
|
# keeping all port hashes up to date is an inconvenience. By setting
|
|
# STRICT_HASH to 'no', the MAKEFILE_LIST can be exluded.
