A new version of the TeXgraph plugin is attached.

With a little help by the developer of Texgraph, P. Fradin, I  have 
succeeded in correcting this little problem and I added a test which let 
you know if you have done a syntax error and what kind of error has been 
done (missing bracket or coma...).

Everything works fine now and the whole thing is really worth trying. It 
is a really good complement to Eukleides, easy to use and efficient for 
plotting, 3D...

Last thing. In the session heading, I would like to know if it is 
possible to add :
1. a link to a documentation for TeXgraph commands which could be placed 
in the /plugins/texgraph folder
2. a folded environnement where I could place a few TeXgraph commands.

Let me know if you need more information or if there are things to correct.

Bye.

# tm_texgraph
# ==========
# bash script for interfacing TeXgraph from TeXmacs
# needs option --texmacs for compatibility with TeXmacs interface 
convention and user information
#
# usage within TeXmacs:
# =====================
# write texgraph-commands within the input line, use as many commands as 
necessary,
# divide them by the "," chararacter, because the ENTER key terminates 
the input and sends it to TeXgraph.
# output is the graph made via TeXgraphCmd, latex, and dvips -E mode.
#
# Temporary file are made in ~/.TeXmacs/system/tmp
