[tlug] File change info on upload to server

[Charles Muller <cmuller-lst@example.com>]

I succeeded in writing a few scripts combining xsl, rsync, gzip, and 
cron to generate some data files on a regular basis that are uploaded to 
my web site (located at a private web hosting service).

One of the guys that regularly downloads my files wrote this:

I looked through my web host's support files and couldn't find anything 
on this, nor could I turn up anything relevant by googling key words. 
Can someone orient me as to what sort of program/application I should be 
looking for?

Thanks,

Chuck
