# This script packages sshyp (from source) for various Linux environments.

# NOTE It is recommended to instead use the latest officially packaged and tagged release.
# NOTE If using Arch, it is recommended to install from the AUR or from the PKGBUILD attatched to the latest official release.
# NOTE As of release fr4, sshync will become a separate package and thus a dependency for sshyp. sshync is automatically installed with the PKGBUILD version.
