GMT shellscript syntax that is not showing up in the blog posts CAVEAT EMPTOR

NOTE -- there is a bit of shellscript syntax that is not showing up in the blog post. There is a shell command

process leftangle-leftangle END rightangle-rightangle plot.ps

that instructs "process" to read the succeeding lines of data until it reaches a line that contains just "END"
In my blog posts the phrase "leftangle-leftangle END rightangle-rightangle" is printing as "leftangle-rightangle"

So you must correct these lines for the shellscripts to work
