NAME
       group - user group file
DESCRIPTION
       /etc/group  is  a  text  file  which  defines the groups on the system.
       There is one entry per line, with the following format:
              group_name:password:GID:user_list
       The field descriptions are:
       group_name
              the name of the group.
       password
              the (encrypted) group password.  If  this  field  is  empty,  no
              password is needed.
       GID    the numerical group ID.
       user_list
              a  list  of  the  usernames  that  are  members  of  this group,
              separated by commas.

BUGS
       As the 4.2BSD  initgroups(3)  man  page  says:  No-one  seems  to  keep
       /etc/group up-to-date.
