# - Implement a routine that checks if installed version is sufficient
# to satisfy the required dependency... right now it's very prone
# to errors and slow.
# - Multiple distfiles in a package.
# - Multiple URLs to download source distribution files.
#
# Default path to configuration file, can be overriden
