I'm sorry to keep harping on about this same issue, but I do find it a real sticking point. When I attempt to learn a new software system (such as a new CAS) I spend a lot of time in the help pages, looking at examples, seeing how things are done; reading online tutorials and introductions. I find help in Axiom very hard to access. To use HyperDoc, and to enjoy the benefits of decent typesetting in TeXmacs, it seems I need two instances of axiom running. And there is no functions/commands help available from the command line (such as there is with Maxima, Maple, Mathematica, MuPAD etc).
And even in HyperDoc, there are very few examples. For instance, I was trying to find the defining polynomial of a finite field. I discovered that there is a command definingPolynomial, but I couldn't find any examples on its use, nor a comprehensive help page about it. There are some simple examples in HyperDoc (calculus, graphics, linear algebra etc), which is incredibly helpful, but there doesn't seem to be this level of help available for ALL commands, as I believe there should be.
From my limited understanding, it would seem that Axiom is superb for the development and implementation of mathematical algorthms (such as Martin Rubey's Guess package), but that it would go even further, and have greater reach in the mathematical community, with more comprehensive, and more easily accessible help.
Please don't take my comments as overly critical; I am speaking from a beginner's perspective. But sometimes it's hard for experts to see things through a beginner's, or learner's eyes.
