16       _e_l_v_i_s_p_r_e_s_e_r_v_e preserves your edited text after _e_l_v_i_s dies.
17       The  text  can  be  recovered later, via the _e_l_v_i_s_p_r_e_s_e_r_v_e
18       program.
19
20       For UNIX-like systems, you should never need to  run  this
21       program  from  the  command line.  It is run automatically
22       when _e_l_v_i_s is about to die, and  it  should  be  run  (via
23       /etc/rc) when the computer is booted.  THAT'S ALL!
24
25       For  non-UNIX  systems  such as MS-DOS, you can either use
26       _e_l_v_i_s_p_r_e_s_e_r_v_e the same  way  as  under  UNIX  systems  (by
27       running it from your AUTOEXEC.BAT file), or you can run it
28       separately with the "-R" flag to recover the files in  one
29       step.
30
31       If  you're  editing  a file when _e_l_v_i_s dies (due to a bug,
32       system crash, power  failure,  etc.)   then  _e_l_v_i_s_p_r_e_s_e_r_v_e
33       will  preserve  the most recent version of your text.  The
34       preserved text is stored in a special directory;  it  does
35       NOT overwrite your text file automatically.
36
37       _e_l_v_i_s_p_r_e_s_e_r_v_e  will  send  mail  to any user whose work it
38       preserves, if  your  operating  system  normally  supports
39       mail.

42       /tmp/elv*
43              The  temporary  file  that  _e_l_v_i_s was using when it
44              died.
45
46       /usr/preserve/p*
47              The text that is preserved by _e_l_v_i_s_p_r_e_s_e_r_v_e.
48
49       /usr/preserve/Index
50              A text file which lists the names of all  preserved
51              files,  and the names of the /usr/preserve/p* files
52              which contain their preserved text.

55       Due to the permissions on the /usr/preserve directory,  on
56       UNIX systems _e_l_v_i_s_p_r_e_s_e_r_v_e must be run as superuser.  This
57       is accomplished by making the _e_l_v_i_s_p_r_e_s_e_r_v_e executable  be
58       owned by "root" and turning on its "set user id" bit.

73       _e_l_v_i_s_p_r_e_s_e_r_v_e will pretend that the file was named  "foo".
