[texhax] textmerge & many files

[Vittorio]

Since 1995 twice a year I've been writing  something like two thousand equal 
letters merging them by means of textmerge to as many addresses ( I also 
created my own *.cls letter file to italianize the letter documentclass too 
"English").

Therefore since then with my unchanged great satisfaction I've being producing 
the pdf files containing the 2,000 letters in one shot at a time.

Now a new need to have  one pdf file for each address at my disposal is coming 
up.

I could I do that? Is there a package able to merge and produce one file per 
address?

Ciao
