- If you're editing a file when _e_l_v_i_s dies, the system
- crashes, or power fails, the most recent version of your
- text will be preserved. The preserved text is stored in a
- special directory; it does NOT overwrite your text file
- automatically.
-
- The _e_l_v_r_e_c program locates the preserved version of a given
- file, and writes it over the top of your text file -- or to
- a new file, if you prefer. The recovered file will have
- nearly all of your changes.
-
- To see a list of all recoverable files, run _e_l_v_r_e_c with no
- arguments.

- /usr/preserve/p*
- The text that was preserved when _e_l_v_i_s died.
-
- /usr/preserve/Index
- A text file which lists the names of all preserved
- files, and the names of the /usr/preserve/p* files
- which contain their preserved text.

- _e_l_v_r_e_c is very picky about filenames. You must tell it to
- recover the file using exactly the same pathname as when you
- were editing it. The simplest way to do this is to go into
- the same directory that you were editing, and invoke _e_l_v_r_e_c
- with the same filename as _e_l_v_i_s. If that doesn't work, then
- try running _e_l_v_r_e_c with no arguments, to see exactly which
- pathname it is using for the desired file.
-
- Due to the permissions on the /usr/preserve directory, on
- UNIX systems _e_l_v_r_e_c must be run as superuser. This is
- accomplished by making the _e_l_v_r_e_c executable be owned by
- "root" and setting its "set user id" bit.
-
- If you're editing a nameless buffer when _e_l_v_i_s dies, then
- _e_l_v_r_e_c will pretend that the file was named "foo".
