In order to build Arboreal, you will need GNU make (on MAC OS X, this
may be installed from the Developer disks).

On GNU/Linux or Un*x systems: type 'make arboreal.jar'; you may use
the shell script 'arboreal' to launch the program. (Depending on your
configuration, you may wish to modify some of the variables set near
the top of this script.)

On Mac OS X: You may use instructions above for GNU/Linux or Un*x
systems. But you'll probably want to build an OS X application
bundle. Type the command 'make Arboreal.app' to make the bundle, and
copy the file from the build directory to wherever you'd like
it. Note that the 'Arboreal.app' target can only be built on OS X.

On Microsoft Windows: Type 'make arboreal-win.zip' to build a
distribution for Windows. The zipped file contains everything that's
necessary to run Arboreal. Just click on "arboreal.exe".

-----------------------------------------------------------------

Arboreal keeps some of its files in ~/arboreal. If you wish, you may
rename this directory ".arboreal"; it will then generally not be
visible, but Arboreal will still find it.
