As the name explains, the code provides widget
representing a tree hierarchy like:

[-] ./
 | [+] CVS/
 | [+] autom4te.cache/
 | [+] checks/
 | [-] src/
 |  | [+] .deps/
 |  | [+] .libs/
 |  | [+] CVS/
 |  |  .cvsignore*
 |  |  Makefile*
 |  |  Makefile.am*
 |  |  Makefile.in*
 |  |  TAGS*
 |  |  glibextra.c*
 |  |  glibextra.h*
 |  |  glibextra.lo*
 |  |  glibextra.o*
 |  |  libinda.la*
 |  |  linda.c*
 |  |  linda.h*
 |  |  linda.lo*
 |  |  linda.o*
 |  |  semantic.cache*
 |  |  tuplespace.c*
 |  |  tuplespace.h*
 |  |  tuplespace.lo*
 |  `  tuplespace.o*
 |  .cvsignore*
 |  AUTHORS*
 |  ChangeLog*
 |  HACKING*
 `  semantic.cache*

You can click [+] and [-] to show and hide the sub tree like
outline mode.
