A capability is a feature of an agent. A capability can be:

• an executable (e.g. Maven)
• a JDK
• a custom capability. This is a key-value property which defines a particular characteristic of an agent (e.g. 'operating.system=WindowsXP' or 'fast.builds=true').
• a Version Control System client application (e.g. Git)

Capabilities can be defined specifically for an agent, or they can be shared between either all local agents or all remote agents. Note that the value of an agent-specific capability overrides the value of a shared capability of the same name (if one exists).
