- Maintenance
  - NeXtMidas requires very little maintenance. There are just a few things to keep an eye on.
    NeXtMidas Save Files
      A state file is created when NeXtMidas is started.
      Running `nmend` at the end of a NeXtMidas session will clean up the state file.
      Many users get lazy and don't bother running `nmend` when they are done.
      The resulting state files get left in the user's home directory with names like `nmsf_4694.msf`.
      They are safe to clean up and deleting them will not affect a running NeXtMidas application. (The only time someone will be affected is if they exited NeXtMidas and then go to back into it later -- they will just lose their current state.)
    Data Files
      It is not uncommon for users to forget to clean up temporary files when they are done using them.
      Periodically it may be necessary to go through the data directories and clean out the "junk". Just be careful, one man's junk is another man's treasure.
    AUX Entries
      From time-to-time file resources may be changed (NFS mounts moved, etc).
      When this happens some of the AUX entries may need to be updated (see AUX for details).
    Java Versions
      When new Java versions get installed the environment variable `$JAVAHOME` will need to be updated.
      Do not remove an existing Java installation if it is in use!
      All NeXtMidas applications will need to be started using a new Java version before the old one can be removed.
