A number of people have written me recently regarding xdelta3 on windows. Fact is, I would love it. One writes:

The syntax is similar to gzip, with the addition of a "-s original_file" argument. By themselves,

xdelta3 -df
xdelta3 -f

operate the similarly to gzip, even without the -s flag.

You're welcome. Thanks for writing in. I have a big pile of mail still to go through, and I have at least one xdelta3 bug report. Stay tuned...
