Some of the demos are for color systems only and will not draw meaningful graphs on mono or grayscale systems. I'm very interested in compilation on other platforms. On some systems, the file pars.c will need to be compiled separately. Use the 'cc' command provided in the Makefile to compile pars.c, then 'make' to resume the compilation. This version will not compile on systems using X11R3 with Motif 1.0x.
Documentation is in better shape but a lot of work remains.
Linux is now my primary development system. Majordomo is a mail list management package, and automatically handles additions and removals from the list. Please use the mailing list for comments, suggestions, and bug reports, but keep in mind that there are 80-90 people on the list. HDF variables with names containing imbedded blanks not read. DX and DY in the yacc grammar refer to X and Y of the current set.
