%description
An R implementation of the cross-platform, language-independent "port4me"
algorithm (<https://github.com/HenrikBengtsson/port4me>), which (1) finds
a free Transmission Control Protocol ('TCP') port in [1024,65535] that the
user can open, (2) is designed to work in multi-user environments, (3),
gives different users, different ports, (4) gives the user the same port
over time with high probability, (5) gives different ports for different
software tools, and (6) requires no configuration.
