= Setup DWT for linux and DMD =

This downloads DSSS+DMD+Tango+Jive+DWT into the current directory and configures them to work. 
Nothing is installed outside this directory. Nothing is changed on your system.

The intent of this script is to get you started.

Howto:
 - Make sure your system has the packages libgtk2.0-dev, libxtst-dev and libgnomeui-dev installed
 - Save this [http://downloads.dsource.org/projects/dwt/setup-dwt-linux-gtk.sh script] to a file into a new/empty directory. 
 - Set execution permission on the file (chmod +x file). 
 - In a console window cd into this directory and start it.

The DWT directories are either downloaded as snapshot archives or as a mercurial working copy if the {{{hg}}} executable is available.
