	\index{system requirements} Splot will run as a PM application on 
any computer running OS/2. An extended DOS version with slightly less 
functionality is also available. Disk space requirements are modest. The 
executable, help, demo and font files take up less than one Mb of disk 
space. The documentation in \LaTeX form and the resultant postscript document 
containing all the figures in the demo directory take up another 2 Mb. 

	To install Splot make a directory for it copy the distribution file 
to it and then use an un-zipping utility to un-zip the zipped distribution 
file. Be sure to use the appropriate flag so that the necessary sub directories are 
created if your un-zipping utility requires it. This should create three sub 
directories one containing the fonts, another containing the example 
programs and a third for the documentation. The executable and help files 
should be in the current directory. There are two included configuration 
files splot.cfg and spexpert.cfg. The default is splot.cfg and contains 
function macros which will fill in prompts for the necessary parameters. 
For an expert Splot user this is annoying since these prompts must always
be erased. Experts should copy spexpert.cfg to splot.cfg to remove the
parameter prompts or customize the parameter prompts in splot.cfg.

	It is recommended that the actual drawing files be put in a sub 
directory of the main Splot directory. 

	To run\index{starting splot} the program type splot (or spltdemo for 
the demo version) on a command line followed by an optional file name(s). 
Alternatively after setting up an association between *.spt files and 
splot.exe files can be dragged to the splot icon to start Splot.
