 In grid computing, and whenever the access to resources may be controlled
 by parties external to the resource provider, users may be grouped to
 Virtual Organizations (VOs). This package provides a VO Membership Service
 (VOMS), which informs on that association between users and their VOs:
 groups, roles and capabilities.
 .
 This package offers libraries that applications using the VOMS functionality
 will bind to.
