Sometimes I wish that, from javascript in the browser, I could ask 
the Jmol applet to let me (javascript) peek into the contents of a 
Jmol command script (.spt) file, preferably before I execute it. Is 
there some way to do this?

If not, do others think this would be useful?

I'm envisioning something like this:

     message file myscript.spt

Rather than executing the script, it would simply message the 
contents of the .spt file. I could then parse the script and behave 
accordingly.

This would be somewhat along the lines of "show pdbheader", which 
messages the PDB file header to the javascript messageCallback function.

I am aware that the script file can set javascript variables using a 
"javascript ..." script command. However, if the purpose of that is 
to inform the browser that, for example, the script  plays a movie, 
it requires an additional knowledgable effort on the part of the 
script file author. If I could just preview the contents of the 
script file looking for e.g. delay or moveTo commands, I could tell 
whether there is movie in the script without troubling the author of 
the script file for (redundant) information in another form.
