xsm  is  a session manager.  A session is a group of applications, each
of which has a particular state.  xsm allows you  to  create  arbitrary
sessions  -  for example, you might have a "light" session, a "develop-
ment" session, or an "xterminal" session.  Each session  can  have  its
own  set  of applications.  Within a session, you can perform a "check-
point" to save application state, or a "shutdown"  to  save  state  and
exit  the  session.  When you log back in to the system, you can load a
specific session, and you can delete sessions you  no  longer  want  to
keep.
