At the lowest one.  Here some snippets of the README:

  libtrash is a shared library which, when preloaded, will intercept
  calls to a series of GNU libc functions and make sure that, if an
  attempt to destroy certain files is made, these won't be permanently
  destroyed but rather moved to a "trash can".  It also allows the
  user to mark certain directories as "unremovable", which means that
  calls to functions which would result in the loss of files under
  these directories will always fail, leaving those files untouched in
  their original locations.

  (This last feature is meant as a higher-level substitute for ext2fs'
  "immutable" flag for use by those of us who rely on other file
  systems.  An important difference is that libtrash allows
  non-privileged users to use this with their personal files.)

  The GNU libc functions which can be overriden/"wrapped" are

  - unlink() / unlinkat();
  - rename() / renameat();
  - fopen() / fopen64();
  - freopen() / freopen64();
  - open() / openat() / open64() / openat64().

  You can individually enable / disable each of these "protections";
  by default, only calls to the first two functions are intercepted.

  [...]

  libtrash recreates the directory structure of your home directory
  under the trash can, which means that, should you need to recover
  the mistakenly deleted file /home/user/programming/test.c, it will
  be stored in /home/user/Trash/programming/test.c.  If you have
  instructed libtrash to also store copies of files which you delete
  in directories outside of your home dir (see libtrash.conf for
  details), they will be available under Trash/SYSTEM_ROOT.  E.g.:
  after deletion by the user joe, /common-dir/doc.txt will be
  available at /home/joe/Trash/SYSTEM_ROOT/common-dir/doc.txt.

I have a cron job which simply deletes files in the `Trash' directory
older than 24 hours (using a script which comes with the libtrash
library).
