It contains lines with the following colon-separated fields: ? group name ? encrypted password ? comma-separated list of group administrators ? comma-separated list of group members The group name and password fields must be filled. The encrypted password consists of characters from the 64-character alphabet a thru z, A thru Z, 0 thru 9, \. and /. Refer to crypt(3) for details on how this string is interpreted.
