WARNING
----------------------------------------------------------------------
As the user sketch files are saved within the DrGeo directory
structure, upgrading to a newer version may result in the lost of user
files (the MySketches and MyExports folders contents).

Before installing newer Dr. Geo version, the user should make a backup
of the DrGeo/MySketches and DrGeo/MyExports folders.

When installing newer version from the Dr. Geo ZIP archive, the user
should request a merging installation. It depends on the Archive
software used to install Dr.Geo.


HOW TO START
----------------------------------------------------------------------
To start Dr. Geo, double click on the file DrGeo.sh.
Check the DrGeo.sh file has the execution flag set.

INSTALLATION
----------------------------------------------------------------------
Linux Dr. Geo is compiled for 32 bits host. To run it on your Linux 64
bits host, you need to install 32 bits compatibility package.  This
package will let you run any 32 bits compiled software on a 64 bits
host.

Depending on the distribution, the package to install may have
different name.

	* Debian < Jessie, Ubuntu, LinuxMint <= 12.04 LTS:

	sudo apt-get install ia32-libs-multiarch

	* Debian >= Jessie, Ubuntu, LinuxMint >12.04 LTS:

	Check you are indeed running a 64 bits system and you have
	access to 32 bits architecture as well:
	
	dpkg --print-architecture
	-> amd64

	dpkg --print-foreign-architectures
	-> <empty>

	Then add the 32 bits compatibility packages:
	sudo dpkg --add-architecture i386
	dpkg --print-foreign-architectures
	->i386

	sudo apt-get update
	sudo apt-get dist-upgrade
