Test page for gnuplot.pl

Most of these scripts are from Alex Woo's gnuplot demo plots

For security reasons (mostly) the following rules have been implemented:

• Lines (including comments) containing special characters such as ` | cause rejection.
• Commands other than "e", "fit", "if", "plot", "reread", "reset", "set", and "splot" cause rejection. (In particular, the commands "shell" and "load" are thus excuded.)
• Only three terminals are supported:

  png	Programmable Network Graphic	A copyright-free alternative to GIF
  postscript	PostScript	viewable using GhostScript
  table	Simple x,y-list output	NOTE: clear _termoptions for this

• Access to gnuplot.pl is restricted to "referring pages" at St. Olaf College. That is, you can use gnuplot.pl only if the page asking for the plot is on the St. Olaf web server.

Additionally, at the present time, the following "feature" limitations, which will be addressed as time permits, are in effect:

• Continuation lines (after lines continued with '\' at the end) are treated as full lines.
• Comment lines containing ` | will cause rejection.
• Semicolons in comments and titles will result in script failure, as semicolons are converted to new lines without regard to context.
