First (and probably last) release of this OOcalc macro.

' This Open Office macro will
' - read all the .xls (or sxc ...) files located in the cFolder defined some line below
' - export each sheet of each file as a separate .csv file, named : filename_sheetname.csv

It is easy to adapt to other input/ouput format.

It works. I needed it, and had hard time to find it on the web, but i'm not the author.
It's mostly copied from
http://www.oooforum.org/forum/viewtopic.phtml?p=194938#194938

so anyone is welcome to improve it and takeover the maintenance :-) .
