In response to my original problem of creating a macro that builds a
file name from several components and then includes it:

   Yes, that is indeed a problem, which I have just corrected on the CVS 
version.
   Notice however that you also should use the "merge" primitive in order to
   concatenate strings.

I have now successfully  installed and run the CVS version of texmacs
on our Ubuntu linux system, and also figured out how to use the merge
primitive to concatenate strings. I can now give another macro as the
argument to \include and get it working. However, when I make a macro
that does this, I still get the blank line. In other words, the stuff
that follows "no luck!" in the document below does not work.  I did a
quick check to make sure I hadn't just missed something simple;
frob-ex differs from in-ex in that it calls the "frob" macro rather
than "include", and it seems to work fine.

  Test.

  Here, we set coding language: \ 
<assign|coding-language|Python><value|coding-language>

  Here, we set up the example-file-name macro:
  \ 
<assign|example-file-name|<macro|name|<merge|<coding-language>|/examples/|<arg|name>|.py>>><example-file-name|hello>

  Here, I do a very simple include with a literal name -- this has worked for
  a long time

  <include|Python/examples/hello.py>

  Here, I do an include using the example-file-name macro from above -- this
  works thanks to Joris' fix:

  <include|<example-file-name|hello>>

  Here, I try to build (and use!) the in-ex macro to do just what I did above
  -- no luck!

  <assign|in-ex|<macro|ex-name|<include|<example-file-name|<arg|ex-name>>>>>

  <\in-ex>
    power

    \;
  </in-ex>

  Now a quick check to make sure I can call on example-file-name within a
  useless macro:

  <assign|frob|<macro|arg|<merge|FROB |<arg|arg>| NICATE>>>

  <assign|frob-ex|<macro|ex-name|<frob|<example-file-name|<arg|ex-name>>>>>

  <frob|fie>

  <frob-ex|power>
