A CMS library is an OpenVMS directory containing specially formatted
 files which CMS uses to operate. You create a library by first creating
 an OpenVMS directory (with the $ CREATE/DIRECTORY command) and then
 creating a CMS library in that directory (with the CMS CREATE LIBRARY
 command). Once you have created a library, it must be reserved
 exclusively for use by CMS.

      (1)  HELP CMS CREATE LIBRARY tells how to create a new library.

      (2)  HELP CMS CONVERT LIBRARY tells how to convert your V2.n
           library to V3.0 format.

      (3)  HELP CMS MODIFY LIBRARY tells how to change the attributes
           of one more libraries.

      (4)  HELP CMS SET LIBRARY identifies one or more existing
           libraries as your current library list.

      (5)  HELP CMS SET NOLIBRARY removes one or more libraries from
           the currently set library list.

      (6)  HELP CMS SHOW LIBRARY displays the directory specification
           of your currently set CMS library or libraries.
