Download the script (xplore.tcl), and move it somewhere in your path
with the execute bit turned on, e.g. in csh notation and assuming you
have a ~/bin in your $path:

	wget http://carma.astro.umd.edu/~tyu/xplore/xplore.tcl
	chmod +x xplore.tcl
	mv xplore.tcl ~/bin
	rehash

To run: execute xplore.tcl, and download the calibrator files by
clicking on File -> Update. This should download the appropriate
files in your ~/.xplore_support/  directory.

The tarball xplore.tar.gz has a bootstrap version of the most recent
calibrator database included.
	
At a minimum you will need TCL/TK, and full functionality will
also require the BLT extension. These may be installed as packages
(if available) or compiled from source code. This should work on
Linux and Mac OS X. If the optional BLT extension is installed, use
the BLT_LIBRARY environment variable to point to its library.

The following are also available:

xplore-CentOS-5.5-x86_64.tar.gz
xplore-MacOS-X-10.5-i386.tar.gz
xplore-MacOS-X-10.6-i386.tar.gz
xplore-MacOS-X-10.6-x86_64.tar.gz

These contain TCL/TK/BLT binaries, compiled for the specified OS
and architecture.
