Here's my proposal,
(let me know if anybody has anything against it and I'm going to stop
immediately):

--> Current situation is....

Signal tcl files are kept in::
/nfs/farm/babar/AWG18/ISL/sx-080702/tcls_sum02/signconc/

Rootfiles produced are kept in::
/nfs/farm/babar/AWG23/ISL/sx-080702/newsig/rootfiles

Rootfiles have CORRECT naming scheme.
*mix*.root contains mix and *nre*.root contain JUST non-resonant
contribution.
Tcl files  NOT: they have been mixed up (some *mix* tcl files contains mix
and some just nonresonant).

--> In order to fix and clarify:

I'm going to create a new directory for tcl file were the naming will be
correct.
(and match actually with root files)
BUT I'm also gingo to leav the old tcl files in 'signconc' dir for
matching with old logfiles.

Then I'e going to update the web page with instruction saying where tcl
files should be taken from.


If that's ok for everybody I'll proceed and make the changes.

Alessio
