[Giovanni Piredda <address@hidden>]

To all: I have written a package which reads a Scheme file with graphics 
commands and places the typeset output in a TeXmacs document, you can 
find it at https://github.com/pireddag/insertGraphics

I think this makes it easier to use TeXmacs graphics.

There is a test file and the pdf output.

There is an error - I think at loading - which does not stop the package 
from working; I would appreciate help to fix it. The error is

<unnamed port>: In procedure struct-vtable in expression (struct-vtable 
obj):
<unnamed port>: Wrong type argument in position 1 (expecting struct): 
#<procedure insertGraphics (graphicsFile)>
<unnamed port>: In procedure struct-vtable in expression (struct-vtable 
obj):
<unnamed port>: Wrong type argument in position 1 (expecting struct): 
#<procedure insertGraphics (graphicsFile)>

(the repetition is in the output)

Giovanni
