Download the script (xplore), 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://bima.astro.umd.edu/carma/xplore/xplore
	chmod +x xplore
	mv xplore ~/bin
	rehash
	
You will also need tcl,tk (wish) and blt installed as packages.
This should work on linux (tested on FC5; yum install blt) 
and MacOSX (10.4, tested using fink's versions of tcl/tk/blt)
You can also manually install the blt package and use the BLT_LIBRARY
environment variable to point to its library.

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

If you are not online, you can download xplore.tar.gz, which has
a bootstrap version of the calibrator files included.
