Leafnode  is  a USENET package intended for small sites, where there are few users and little disk space,
       but where a large number of groups is desired.

       Checkgroups is the program which parses checkgroup scripts to include new/updated group descriptions into
       the active file (which is usually /var/spool/news/leaf.node/groupinfo).

       Checkgroups sets its real and effective uid to "news".

LN_LOCK_TIMEOUT
              This variable is parsed as an unsigned integer value and determines how many  seconds  checkgroups
              will  wait  when  trying  to  obtain  the lock file from another leafnode program. 0 means to wait
              indefinitely. This variable takes precedence over the configuration file.

checkgroupsfile
              is a file which contains the newsgroup  name  and  the  description  on  one  line,  separated  by
              whitespace.  Checkgroups  scripts  are  sometimes  sent  out  by news administrators (e.g., in the
              bionet.* hierarchy).
