Xymonfetch, msgcache and personal scripts

Hello all,

I managed to make the xymonfetch work through a ssh tunnel and the default
tests are now visible in the xymon page (thanks to Thomas and John).
But I have personal scripts that I used to launch via clientlaunch.cfg and
I do not know how to tell the script to write data locally (in msgcache)
instead of sending the datas to the xymon server.
Thank you again for your help.

Pierre
