Nexus manages software artifacts required for development, deployment,
and provisioning. If you develop software, Nexus can help you share
those artifacts with other developers and end-users.

Nexus requires a "nexus" user and group; create these before running
the SlackBuild script. Examples:

# groupadd -g 252 nexus
# useradd -u 252 -s /bin/sh -d /dev/null -g nexus nexus
