To begin with, I think that everyone who works on the "plt team" uses  
multiple collections directory, so I'm confident that success can be  

Second, I was unable to reproduce your problem.

Third, looking at your code, (or rather, running it), it appears that  
you have not done a direct cut-and-paste into the mail message.  In  
particular, the "essai.scm" file you include is incorrect, because it  
wraps the identifier *essai-defined* in parentheses.  This doesn't work  
in MzScheme, MrEd, or DrScheme. I suspect that the code you used to  
test this was slightly different than the code you included in your  
e-mail.  Furthermore, I see that drscheme is complaining about line 4  
of your info.ss file, when the one you include only has 2 lines.  Is  
this also a case of mis-pasting?

best of luck,
