Portability

As I mentioned earlier, IPE uses the XView toolkit developed by Sun for X Windows. Since X and XView are distributed freely through MIT and have been ported to many machines, most anyone interested could take advantage of IPE. While all the examples I will show here use SEP data processing and graphics programs, I've taken care to avoid any SEP-dependence in IPE itself. Any user who has programs to process data and display results under X Windows could use IPE. The only potential hitch would be the mechanism by which parameters are passed to a program, but the amount of code that would have to be modified to handle another method would be quite small.
